Not their problem. They, and especially their backers, expect to be well out of it by that point. The rich don’t really think about the future; they think about how things were in the past, and how to keep it going, but they don’t really plan or fret about the future because they don’t have to.
If you want this problem to be fixed sooner, the government and their backers need to start being afraid enough for their bank accounts, if not their lives, to do something now.
That’s how we got the modern welfare state: the rich and their pets in government were afraid they’d get Russia-in-1917’ed and begrudgingly put in the supports needed to prevent people from being that pissed off. After all, we’d just had a world war and there were millions of vets returning with PTSD and training and an informal support network, and they weren’t going to put up with a repeat of the 1930s.
Every action since then is the rich trying to claw back the New Deal and it’s equivalents in other countries.
