Its all paper cash. What people need to worry about is the folks with their asses mortaged to the hilt so they can live in a 2,000 sq foot house that cost them 500,000 bucks with no yard. When that bubble pops, ****s gonna hit the fan. A whole lot of people have borrowed against artifical value in their homes. At no other time in history have people been able to go out and rack up a 100,000 dollars in debt with nothing more than a signature and a house. Its gonna hurt when it happens, and it will happen.
