I don't like that title of this article as the article is really showing that Buffet's track record and investment strategy are proof that US markets are irreparably broken due to the lax enforcement of anti-trust in the last 30+ years. It's not that Buffet is encouraging this or actively fighting a free market, he set a very conservative strategy of investing in monopolies and then all sectors fell to monopolies. He figured out how to beat the house and the house didn't care. Good for him, bad for non-billionares...
