Microsoft Corp. (MSFT) co-founder Bill Gates believes that extremely wealthy people such as himself should be forced to pay “significantly higher taxes.”

In an interview with CNN, the billionaire philanthropist said he has "paid more taxes...than anyone else,” but still urged the U.S. government to squeeze even more out of him and other super-rich individuals. Rather than complain, Gates claimed that wealthy people should see it as their duty to contribute more toward society and help foot the bill for those less fortunate.

"I need to pay higher taxes," Gates, the second-richest person in the world behind Amazon.com Inc.’s (AMZN) Jeff Bezos, according to Bloomberg’s billionaire’s index, said in the interview. "I've paid more taxes, over $10 billion, than anyone else, but the government should require the people in my position to pay significantly higher taxes," he added.

Gates, who previously pledged to give away at least half his money to philanthropic causes, made the comments in reference to the recent Republican tax overhaul. Rather than help America’s working and middle classes, as President Donald Trump asserted, Gates fears that the new tax regime will only benefit corporations and the nation’s wealthiest people.

“It was not a progressive tax bill. It was a regressive tax bill," he said. "People who are wealthier tended to get dramatically more benefits than the middle class or those who are poor, and so it runs counter to the general trend you'd like to see, where the safety net is getting stronger and those at the top are paying higher taxes.”

During the interview, Gates was also asked for his thoughts on “rising inequality” in the U.S. Microsoft’s co-founder responded that inequality is an issue that “all advanced democracies have to think about that." (See also: Tech Giants Inviting Govt Intervention: Bill Gates.)

"You still have about a sixth of the population living in conditions that should be very disappointing to us, and government policies need to really think, 'Why aren't we doing a better job for those people?'" he said.
