The rich are always going to have an advantage towards staying rich. Heck, the people that voted for candidates who talked about trade policies and immigration cheered a massive corporate tax cut.
True, we will always have the rich in our society. HOWEVER, the rich got richer at stupendous rate in the last few decades, while the rest got poorer at increasing rate.
I wonder how the charts look if you graph them on a log scale. Wealth concentration is exponential by nature.
