This is a very tricky subject. Generally, under capitalism, when productivity increases, pay also increases regardless of who is responsible for the productivity increases. Better to be an auto worker today than 100 years ago-right?. Here's how it works: if companies put in robots that do the work of 100 people the companies save themselves the pay for 100 people. But, all the new money means they can afford to pay remaining workers more which they must do or lose their best workers to those who will pay them or share with them the most money possible out of their new profits. Thus, capitalism is a workers best friend, exactly the opposite of what libcommie Marxist Democrats would have you believe!
