Bernie Sanders and Bill Gates
Sen. Bernie Sanders, left, and Microsoft's Bill Gates.
  • Bernie Sanders says government should "tax the robots" that replace workers.
  • In his new book, Sanders references Microsoft's Bill Gates' ideas on this issue.
  • "We're going to need to adapt tax and regulatory policies" to address robots, Sanders write.

You've heard Sen. Bernie Sanders say — and probably shout — that he wants to tax billionaires. He also wants to tax robots.

In his new book, the Vermont independent writes that he supports establishing a robot tax to account for the impact of automation on workers.
