The "values" of the houses were going up because of the legalized financial crimes that were made legal so that the parasites wouldn't have to take the losses they created in the financial markets. There never were real market forces (demand outstripping supply) driving the prices up, the prices were driven up by the prospect of collecting fees and leveraging the debt created by the transaction.

Tens of millions more losers were made in The Greatest Robbery in History than won even a little bit and literally everybody that still earns a paycheck, or will for decades to come, be paying off the winners... unless there is another collapse... the game isn't over...
