The funny thing is, for all people that claim that things are getting worse, there are actually objective metrics that show things are in fact better than they've ever been in many areas. People tend to just focus on the specific local negatives, without realizing how good things actually are. It's almost the reverse of what they are claiming - people are so used to how good things are, they don't notice it.
Now, this isn't to say that there aren't areas or aspects of society which are in fact declining, because they are. While consumer cost of goods is really quite low, barriers to creating new businesses are very high. There is no longer any expectation of privacy, mob mentality is rampant (public and even private figures are immediately eviscerated by the internet basically for being human and making mistakes or not speaking only with 'approved terminology'), and the internet provides such fast access to information that the extreme is easy to highlight.
Basically technology in general, and the internet specifically, has been a catalyst for both good and ill - it makes all things easier.
Regarding another economic hot-button: wealth equality is a bit of a red herring. It definitely impacts power structures, but as far as absolute economic stability of the low tiers, the more important thing isn't the ratio of minimum income to max, but the absolute level of the "most poor". Consider that in the US, we have massive wealth inequality. Yet the most destitute poor in this country are still more wealthy than the poor in, say, Haiti. The poor in this country don't generally have to worry about fresh water or cholera or fighting feral dogs for scraps of food. The US doesn't have slums like in the tropical poor countries - yeah we call areas slums, but they generally have power, water, sewer, and the like. The houses in US slums are not literally built out of trash.
I don't mean to say "there are areas worse off so we shouldn't try to keep/make our area good/better" - what I mean is that whining about the entertainment fiasco of the bread-and-circuses administration is a massive distraction from things that really matter. Arguing / philosophizing about which party (or party structure) is better is white-tower kind of bullshit when there are people who literally don't have food nearby to even steal, let alone beg for.
I'm not saying here that we need to change the world - at least not in the media-visible sense. I'm saying change the world by trying to touch one person in your immediate sphere. Assist them, even with a little personal sacrifice. Do it because other people are valuable, not because "you have to stop the tide of societal decline". If you've been blessed with much material wealth, share it. If you don't have material wealth, share your time. And don't fret about what other people do or don't do with their wealth or time... you can't control that in the first place (and trying to distinguish "telling people to do X for the greater good is acceptable, it's only telling people to do X for personal gain that's bad" is also bullshit).
Also remember - everyone is destitute in their own way, be it emotionally, scars from the past, dealing with a bad environment or crappy relationships or depression or social issues. Hell, even the "super rich" probably have all sorts of personal demons they don't let others see.
