For the rich, there are multiple loopholes to avoid paying taxes. And most cases of loan default are done by the ultra-rich and not the poor or the middle-class. Both the left-wing and right-wing political parties are united when it comes to maintaining the status quo as far as the tax loopholes are concerned. The right-wing parties tend to decrease income tax, while the left-wing tend to increase them. But both these groups keep loopholes available to the rich, and in the end the rich will have a tax burden that is proportionately lower than what the middle-class is having.
