the root cause of the financial collapse on the front end was the housing bubble, and on the back end, the root cause was the 40-to-1 leverage ratios hidden away in securitized debt and the shadow financial system which came crashing down when housing prices turned downward to end the bubble
a bubble occurs if everybody expects, and expects future buyers to expect, that future prices will increase above that otherwise determined by the fundamentals of supply and demand
contrary to popular belief, a bubble does not require credit, or even fiat money to exist, and could occur on a gold or barter standard, fueled by income or savings instead of debt, however, "innovative financing" based on 40-to-1 leverage ratios can expand a relatively harmless, correctable bubble into a financial collapse like the current one
every dollar of default at the homeowner level is multipled by 40 throughout the system wherever the toxic debt exists, which caused panic and a dramatic contraction of credit as $2-4B of wealth evaporated from homeowners and shook the financial system to its knees
blaming individual home buyers for the crisis is nonsense - expectations of rising house prices were pervasive and decisions to seek the high investment returns were rational and no different than other investments <i>in light of a government policy dictated by the private housing sector through lobbyists, including those with Fannie Mae and Freddie Mac, that specifically denied the bubble, encouraging it instead with low interest rates and expanding it dramatically through deregulation of the financial industry</i>
the lax qualification standards for loans, low teaser rates with exploding resets and reams of outrageous fees and commissions for nothing in return were all <i>supply side phenomena - not demand side - designed to redistribute bubble-driven profits away from homeowners to the financial and real estate sector</i>
blaming the buyers for purchasing homes under these conditions as "too good to be true" is mistaken because it was pervasive as accepted practice and obviously was true, even without the hard sell - that many new homeowners could not be wrong no matter the terms and conditions <i>which despite how egregious, could have been largely offset had housing prices continued to rise</i>
when the bubble burst with declining prices is when the unraveling began, but just because some homeowners were leveraged out on a knife edge of risk when prices turned downwards doesn't mean it was their fault - the people that sold it to them multiplied out that risk by forty-fold and in that context are forty times as guilty, or even more given that near the end, denials of the bubble turned to "who could have known" flat out lies
