Ever tried the Midwest? Because I've seen better than what you just described, better by far, and it was on 50-70k income. I don't know where you're pulling your numbers from, but I've seen plenty of people in that income range living in better conditions than you claim possible.
Everywhere I've lived and heard of in the Midwest, outside of cities there's not much in the way of troubles with crime, 50-70k is a middle-class income, not just-above-abject-poverty like you seem to think it always is, and you can live perfectly comfortably on said income with multiple cars, a good house, and some amount of safety cushion (Though the cushion can be thin if you didn't make great financial decisions earlier-on in life). Even going unemployed isn't a financial death sentence, I've seen people recover without losing everything, or almost everything, as you seem to think must happen.
So seriously, where are you getting your information from? What places are actually that horrible? You've successfully gotten me interested, albeit in a minorly horrified way.
Lived in Indiana most of my life, here. Dead center of the midwest.
I grew up in a very small town in Indiana from ages 8-16. Like... drive through it in less than 5 minutes, and outside of that you are in get-in-your-car-to-talk-to-neighbors territory. There is not a single stop light anywhere. There's a gas station at either end, an elementary school, and it barely qualifies for its own post office. Fillmore, IN if you want to Google Maps it - I believe the place hasn't changed much in 20 years. Deteriorated further from what I've heard. The high school I went to was a 30 min drive away. Collected students over a huge geographic area. And only had about 640 students grades 7-12. So I can tell you from personal experience that rural people in Indiana are quite violent, and drug problems are rampant, especially meth and heroin. Authorities in such places operate very much on a good ol' boy club basis, and those who fit in with the culture there could and did get away with doing just about anything they wanted with those who didn't. The school had a 60% graduation rate (40% for women), was infested with cockroaches, and everything was horribly outdated. I could also name at least one teacher who was definitely a pedophile, and someone I knew back then has pictures of the principal hitting on a student. The house I lived in there was ~130 years old and full of holes, including a giant gaping hole above my bed that I could feel breeze through from outside. The plaster in the walls had horsehair in it. It was heated by woodstove.
But yeah... it's cheap to live in places like that. My dad's an incredibly intelligent, hard-working guy, and my mom did a great job supporting his ability to focus on career. They saved money living out in the middle of nowhere, while he worked his way up the ladder. He just had a 45 minute one-way commute to deal with every day, but this was back when gas was half the price it is now. In the winter, that meant it sometimes took him a couple hours to get home through unplowed rural roads. A few times, he took a shovel with him, and had to dig his own way through.
My dad's now soon to retire from being global head of a small department of a major corporation. When I was 16, my parents bought a nice big house in a prosperous Indianapolis suburb. Where I was seen as the bullied weird-but-genius kid in Fillmore, I suddenly felt stupid going to school here. It was great until I had to move out on my own.
I was making just under $30k when I moved out with a wife and kid, and living in this area was not cheap. Gas prices had doubled over the last few years, so a ridiculously long commute wasn't worth it anymore. Plus, I was commuting not just to work, but still going to school at the same time at a commuter campus in downtown Indianapolis. And we didn't want our kids to get the same kind of abysmal education experience I described above. So we moved into the cheapest apartments around. We witnessed drug busts, and kids threatening each other with guns. There were break-ins and rapes in our neighborhood. My wife tried to get work, but could never find anything that wouldn't require paying for daycare, which would cost more than she would make. So we lived on my income alone, and wracked up $50k in student loans to make up the difference. And the job I was working made me horribly, horribly depressed. As in, I kept a log of how I spent every minute of my time to protect myself against metric-based micromanaging, and often spent my days floating through violent suicide-just-to-make-the-motherfuckers-feel-bad fantasies.
I graduated in 2008. The official year of the great recession. So I ended up fearfully stuck where I was, while everyone around me was getting laid off or taking quit-with-severance options. It's by sheer luck that I'm doing better now. A co-worker friend found another job in the same industry, and with his recommendation, I was able to follow. Then the team I was placed on suffered a morale crisis and everyone quit, so less than 2 years in, they promoted me to manage the team and re-build it from scratch. Which I did very well. It just involved giving my life up entirely to work.
I'm now squarely in that 50k-70k bracket we're discussing. I won't say what I actually make, because it's standard in the industry I work to fire anyone who has been found sharing information about what they make... and one of my bosses actually used to play DF. I'm doing better materially than almost everyone else in my social circle. Who I rarely actually see, because I don't have time for them. I keep loosely in touch by scrolling Facebook a couple times a day and trading comments.
So we just bought our first vehicle of our own last year, because the old junker my parents let us use was reaching the end of its life. We also bought our first house last year. We had no fucking choice, because rent has skyrocketed about 50% over the last few years. And we wouldn't have been able to do that if my parents hadn't agreed to help us with down payment. We would have been truly fucked. Now by appearances, we have all the trappings of being a successful family. But car payment + mortgage is literally half of my income, even making as much as I do. And remember that if we were still trying to rent, it would be worse. On the rest, we're just able to get by rotating minimum payments on debts wracked up in the past, and still eat decently well/see a movie or something once in a while. I haven't been to a dentist in 4 years. My wife drives on a suspended license, because she got a ticket a few months ago we haven't been able to pay. When she's even physically capable of driving, because of aforementioned back issues that we can't pay to tend to. The last 3 neighborhoods we've lived in have all been middle-class-ish... but... we still see lots of drug activity and have been broken into and robbed twice. I strongly suspect there was some human trafficking going on a couple houses down from us the last place we lived.
I can't say we're not doing great. We're making it. Until something happens that fucks up the delicate balance we've been able to maintain so far, thanks to a couple major strokes of luck in my career, being born to successful parents, living in a low cost of living state, etc. Otherwise, we'd be fucked. And we're still one bad stroke away from being fucked, always. Like say my diabetic kid's medical costs go up, or I'm put out of work for more than a week for any reason. But yeah... making it so far.
But like I said before. What a fucking pathetic situation we're in, where my story is a decently successful one for my generation. It makes me angry to know that this is what success by hard work and a lot of luck looks like. To know people who work even harder and are more capable than I am who are doing worse in their lives. There's no excuse for it. And this isn't a warzone. We're not a country that is only beginning to modernize. This is simply a country that's been losing its class warfare for far too long.
And the midwest is a shithole that I've longed my entire life to escape. Just had to illustrate that for you. I'm sure if I lived in rural Indiana on 50-70k, I could live like a king... but how the fuck do people actually live out there. There's no work. And I'd have to live in the truly middle-of-nowhere outside of town, because those small towns are violent drug pits of despair. Suburban Indiana is cheap by most U.S. standards, but not comfortable on this income for someone with kids or who comes into a middle-class position from less than ideal previous circumstances. And I still have to worry about getting robbed or my children kidnapped.
