"Springkaan, why do you think the government has the power or the cash to prevent a crash? A 20% fall translates to a trillion dollars, twice the Greek national debt."
Big deal so a 20% fall translates to a loss of a trillion dollars to use your figures - for the most part it is largely irrelevant and many of those have no mortgage, and most will mortgages won't be forced to sell. So the reality is the actual realised loss is SIGNIFICANTLY smaller.
