I think right now the government is more concerned about getting out of the economic mess than it is about coming after every person that makes money through multiple avenues. We had a huge discussion about this in my Political Science class. The United States is too close to becoming a failed state. The more money we make means the more money going into the economy. The IRS may not get a big chunk of money for our taxes, but they get it in other ways. I think right now they just have more to worry about. It truly is a loophole, but it is not worth the time right now to focus on going through each person and trying to figure out how much they made from each employer. I don't see the loophole changing anytime soon.
