Jeff Bezos became a billionaire by making the lives of Amazon’s customers better. Sam Walton did more to improve the lot of poor families than most government programs. (Those guys at least built something. Why does no one complain about America’s grandpa Warren Buffett. He just shuffled around money, plays with warrants and options (while telling others not to) and makes a couple hundred million by going to Congress…
Shuffling money around is absolutely an important part of the economy. It moves resources from unproductive or low productive companies to higher producing companies. The name for this activity is called "Capitalism". One could argue that Warren Buffet should pay higher taxes. And he would agree! But unless you find capitalism itself unethical there is nothing wrong or underhanded with searching for undervalued firms…
My biggest complaint is that that instead of paying higher taxes Warren Buffet could maybe not jawbone Congress into bailing out AIG. AIG should have gone bankrupt and Goldman Sachs (and their other counterparties) should have borne that pain, and possibly gone bankrupt themselves. Instead Warren Buffet refuses to come to the rescue of AIG, comes to the rescue of GS, and then tells Congress that the economy will freeze up if AIG and other banks aren't bailed out. That is not efficient allocation, that's crony capitalism.
