The problem that ties all of the shortages together is cost. We can fix one problem, or another, or another, but in the end, the solution costs more. Our wages don't rise though, espeically those of young people.
So, in the end, the problem we end up with is financial. Young people can't afford to pay back their student loans, or to buy new homes and cars. The government can't collect enough taxes to pay all of the benefits it has paid out. At some point, something has to give.
Many economies have collapsed in the past. Quite often what happens in that the government collapses--think of the Former Soviet Union. People are not looking in the right direction to find the problems that are building up.
