Bruce Bartlett amplifies on why he's been calling for a rewrite of U.S. tax codes to make them fairer. That oughta be done. The problem is that every time we change the tax codes, someone — usually very rich people — have the clout to have the new codes say that their kind of income isn't really the kind of income that ought be taxed.
This is not to say that all income ought to be taxed equally. Heaven forbid. As we all know, it stimulates the economy and creates jobs for all if we keep taxes low (or better still, eliminate them) on money earned writing about pussycats who eat lasagna.
