Actually, the cause of the Bush Mortgage Bubble has been addresed. The Bush Mortgage Bubble was people buying homes they could not afford. Just so you know, the way you put somebody in a house they can’t afford is to not check their income. That’s why over 50% of all loans in 2006 were “stated income” loans. (yes, more than half of all loans in 2006 didnt verify the borrower's income)
Every regulatory effort since the Bush Mortgage bubble has been for banks to verify the ability of the borrower to repay the loan. That’s the key part of Dodd Frank. Here’s the Fed’s rule specifically addressing subprime No Doc loans.

"Second, lenders are prohibited from making "stated income" loans and are required in each case to verify the income and assets they rely upon to determine borrowers' repayment ability. Lenders must also verify and consider the borrower's other debt obligations, such as by using a credit report. The rule is intended to ensure that creditors do not assess repayment ability using overstated incomes or understated payment obligations"
As far as recessions go, cons keep wishing for a recession and republicans actively try to cause one. So you guys just keep hoping. I’ll just keep rolling in the dough.
