He doesn't really consume the money he gathered. So the fact that he owns so much just puts a slight deflationary pressure on the economy, nothing more. Of course he could use the money to buy goods and services taking them away from poor people, or purchase political power to achieve harmful goals but as long as he doesn't do that too much his hoarding is no issue. It's not like government can't just print more money and give it to the poor if it wants to.

Besieds his money doesn't sit it in the bank. He has it in short term tresury bonds. Which means he basically lent it all to the government. If this money is not used to help the poor then blame the government because it controlls Warren Buffett money until it gives it back to him.
