The aim of promoting low down payments is to push prices back up so that fewer houses are going to be in negative equity and fewer people are going to walk away from the mortgages. That will save the from taking a loss on their junk mortgage loans.

Debt deflation is when there's less money that people have to spend out of their paychecks on goods and services, because they're paying the FIRE sector. Oil going down is a function of the supply and demand of oil in the market. It's a separate phenomenon.

When you say "paying the banks," what they really mean is paying the bank bondholders. They are basically the One Percent.

High prices can be the result of speculation, and maybe plunging prices can be attributed to the end of speculation, but low prices over time aren't caused by speculation. That's oversupply, mainly by Saudi Arabia flooding the market with low-priced oil to discourage rival oil producers, whether it's Russian oil or American fracking.

If the economy is growing, people want to employ more workers. If you hire more labor, wages go up.

The fact that you have government-guaranteed student loans has created a whole new sector in the American economy that didn't really exist before - private for-profit universities that sell junk degrees that don't help the students. They promise the students, "We'll help you get a better job. We'll arrange a loan so that you don't have to pay a penny for this education." Their pet bank gets them the government-guaranteed loan, and the student may get the junk degree, but doesn't get a job, so they don't pay the loan.

Actually, high housing prices don't help the economy. They raise the cost of living.
