Warren Buffet is the closest thing there is to a “good” billionaire. He made his money through responsible investing (investing in stocks based on the quality of the company and product rather than demanding short-term profit at the expense of future sustainability like the rest of the market), openly campaigns for higher taxes on the wealthy, pays his employees a generous wage, and was one of the first to join Bill Gates’ Giving Pledge and the only billionaire I know of to immediately follow through and donate away huge swaths of his fortune, while the other Pledges only gave vague promises to donate a portion of their wealth to charity at some point before they die.

He’s not perfect, but if more wealthy people were like him the world would be a much better place.
