At this point a blind can see that this trend is not sustainable, i'm of the opinion that we have a runaway indicator. People that want to see this trend continue are the same ones that act dumbfounded when next students/occupy wall st/BLM civil unrest happens. Why are those plebs are not happy with their ever shrinking share of wealth, i tried showing them youngins (with college degrees still living with their parents because they can't afford to live on their own) rolling's statistics that show that they're better off in absolute dollars but they just ignored me and continued to sharpen their pitchforks. I'd rather not have to live in enclaves and hire private army to protect myself from them. Soviets provided cheap stimulus (vodka) to control their plebs, we can provide opioids but would need to take away their healthcare first.
It is very sustainable, someone else's having wealth does not take anything away from you, the opposite is true.
Nobody is dumbfounded that young people protest something they are too immature to understand fully, especially when you know how they were brain washed throughout their years of education. There is a reason people tend to become more conservative as they get older, experience.
The plebs are not happy because they listen to too much propaganda on liberal media and Twiiter and they've been lied to their whole lives about what they were entitled to.
The youngins with college degrees who can't get a job were sold a lie. In the 1970s only 10% of people had degrees so it was a good way to secure a job. Now 35% of people have degrees and a large portion of those degrees are in fields without enough jobs for said degrees. Not many scientists or engineers are having trouble finding jobs.

The wealth held by wealthy people is theirs and 0% of their wealth is or ever should be yours. There is not a limited wealth pie where it gets distributed amongst the population. There is unlimited wealth for those who create it and they owe none of it to those who did not create it.
The wealthy do owe taxes and the top 50% pay 97% of the federal taxes already. Even if they pay 100% of the taxes, you are still not going to change the wealth gap and you are still entitled to 0% of their wealth.
