I think it's already a done deal. Millennials aren't as young as they seem (over 30) and as the own a minuscule percentage of US household wealth. The numbers are incredible.
"Indeed, at a median age of 35, Gen Xers owned just 9% of the nation’s wealth in 2008 — less than half what boomers had at that age. And millennials will have to triple their net worth in the next four years to catch up to Generation X at 35, and increase their wealth sevenfold to catch up to boomers at that age." https://www.marketwatch.com/story/this-depressing-chart-show...
The funny thing is that across that millennials seem to love politicians that HATE them.
Obama's big thing was Obamacare which was basically a tax on the young (force them to buy insurance to subsidize capped insurance rates on older people). Bernie's big thing is expanding Medicare and Social Security.
So, I don't see things changing any time soon.
