It's not just that prices are high - it's that salaries haven't kept pace, there is more unemployment than they count based on their criteria, nobody is buying bonds, nobody is building homes, suicidal and desperate business owners and home-owners/buyers are taking out untenable adjustable-rate mortgages.....

All of these many-faceted factors are coming together and it's like that scene in the classic Tom Cruise movie "A Perfect Storm". All we can do now is pray. (They all died tho)
