Reading Krugan’s article, the point isn’t so much that he hates robots as that compensation of labor is dropping relative to capital. The return of manufacturing to the U.S. isn’t going to bring back lots of high paying factory jobs for blue collar workers. Instead we have lots of low paying service jobs. In order for these working people to enjoy dignified lives, we have to find ways to improve their compensation, such as increasing the minimum wage, or taxing those you own assets and are being incredibly well-compensated to provide government services and assistance to make up the difference. The challenge is to make it possible for the broad base of the population to be able to afford all the stuff our technology can produce.
