Workers are cheaper and smarter than machines (even at the vast sum of $15/hr), and expected to maintain themselves.

When a business manages to automate in some small way that allows them to reduce staffing, that's a good thing. It's hard to do. If enough of them do, raise wages again to make up for it. In the year 3021, every 10th person works 10 minutes a day while the robots hum, and with their wages can take care of 9 other people.
