I was not claiming that "return to the way it was 4 years ago" was the desired end state. The idea was in fact to stop the bleeding. It's also sad to me that there is still so much despair "yeah ok this is a change, but it's going to be even worse." Why so much resignation? We should use this opportunity to start putting in place the systemic changes to help avoid something perceived as worse in the future.
"Pay a living wage" - this is a systematic issue, and can't be solved easily. It's almost like the prisoner's dilemma - if a single company A that is making a profit starts to pay its workers more, that won't help that company - all that extra money will (all else equal) go to the profits of the companies that sell things to the employees of company A. So maybe it will help Employees A for a short time, but not in the long run. It will take "enough" companies paying their workers more, so that all companies' employees get more pay. Or it will take some other change, like UBI, or even something more drastic like tying money creation to production, rather than to debt.
Incidentally I would say 75% of the issues are economic and 25% are people - even progressives - not wanting change imposed by someone else (e.g., "someone else moving into the neighborhood").
The economic issues really all boil down to two conflicting tensions: people who work want to keep the majority of the output of their work for themselves, but people who are out of work want some kind of social safety support. Some people think the safety support should be there for any reason, but others think it should have some criteria like you have to "pay in" first to get a payout.
That all said, none of this can be solved in 4 years, or even 8 - any change is likely to be a generation thing. Keep in mind that this election is the first time that people born post-9/11 could vote - so we are seeing that "generational" effect. Even if you get a revolution, which will destroy things very quickly, it will take a generation to rebuild after that change.
However, even if we know something takes a long time to change, that doesn't mean we should delay trying to change it - we should start now so the time to final change is minimized.
