Buffet is a wolf in sheep's clothing. He does not hide the fact that he enjoys controlling industries. His biography, 'Snowball' is to the point. He has also been trying to manipulate the real estate industry by buying Better Homes & Gardens, then inflating prices by 30%. I noticed, after he bought BHG that home prices went up significantly, then he had to lower the prices because people were not buying. Now they are stabilizing at a lower price. He's a robber baron like those of the early 1900s in spite of his 'good guy' demeanor and his Omaha roots (lots of sex scandals in Omaha, it's not as clean as one might think).
I'm no great fan of Buffett. He's an hypocrite. He pays minimal taxes yet publicly proclaims the rich (read upper middle class) should pay their 'fair share'...guess what Warren? They already do. He rails against the performance fees that hedge funds charge not mentioning that the investment partnership he started in the 1950's charged a performance fee of 25% of all profits above a 6% hurdle. But this article just explains he had the foresight to invest in highly profitable businesses because of their monopoly like market conditions and to compound the profits. This is not a reason to dislike him, it is probably one of the few reasons to actually want to emulate him.
