Congress is about to sell us the biggest fraud in American history. It's been highly touted as an economic stimulus bill that will help millions of Americans. As part of the bill, Congress is set to rush through an increase in the mortgage loan limits for Fannie Mae and Freddie Mac (and Federal Housing Administration insurance, too) - from $417,000 to $729,750 - the first step toward a massive financial disaster in which taxpayers will end up paying through the nose. Now, thanks to Congress, junk bond investors will be able to pawn off their bad debt to Fannie and Freddie. This shift will certainly doom Fannie Mae and Freddie Mac, so don't be surprised if we, the taxpayers, have to bail out poor Fannie and Freddie - to the tune of more than $1 trillion. The irony here is that the collapse in housing prices could make Fannie insolvent even without raising the loan limit. Increasing Fannie's limit is like going on a spending spree with your credit cards because you know you are going to file for bankruptcy in a few months. Only here the taxpayer is left holding the bag. Our children will pay interest on this debt in perpetuity. It is our debt. It is inescapable. In the coming months, Fannie and Freddie will buy up mortgages based on old, fraudulent appraisals and on loans with bogus inflated incomes. Unfortunately, many of these loans will still default. Expansion of Fannie and Freddie's reckless lending is exactly what Congress wants because it's plausibly deniable. Teary-eyed lawmakers can take to the airwaves a year from now and declare: We had no idea Fannie could go under, but we can't cut and run now. Those same lawmakers won't mention the fact that they get paid far more by real estate lobbyists than they do from our Treasury.
