You're right about the 80/20 split to get around PMI, but greed is not what got us into this mess. Social engineering, i.e., a Democrat administration and legislature that didn't think it was "fair" that successful people could afford a house, while unsuccessful people couldn't, is what got us into this mess.
Don't blame greed. Greed is liberal-speak for capitalism. The only people who blame greed for America's problems are those who are greedy, but who are not willing to sacrifice and work hard to satisfy their cravings.
You don’t think it is greed that caused people to buy houses they couldn’t afford with no money down? I do.
I just read your great comment and especially liked:

False.
Greed explains the mad dash for short term mega-profits with the result of mid-term bankruptcy.
Capitalism and the free market system is supposed to reward long term profitability, not get-rich-quick schemes.
