Sen. Bernie Sanders has been one of Amazon.com Inc.’s staunchest critics. That’s why a rare instance of praise from the Vermont senator and 2016 presidential candidate is notable, following the U.S.’s second largest employer’s announcement on Tuesday that it is raising the minimum wage for all U.S. workers to $15 an hour:

“ ‘What Mr. Bezos has done today is not only enormously important for Amazon’s hundreds of thousands of employees, it could well be, and I think it will be, a shot heard around the world.’ ” — Bernie Sanders

“Today, I want to give credit where credit is due,” Sanders said following Amazon’s announcement.
