The worker would be using vastly less resources. In my life I spent so much money/time/energy commuting to work and everything that entails having a job, not to mention time wasted in adult education, post grad degrees, trainings, etc I would never need as non-working welfare person. Heck, college is questionable as well. So there's a majority of my debt/spending there, ignoring my mortgage. Also, a robot doesn't need breaks, a cubicle, vacation, etc so its using vastly less resources.

Businesses would be forced to compete so those savings would be passed to the consumer which means a lower cost of living. Not to mention taxing automated businesses to pay for this new welfare/UBI/whatever.

Seems like a win-win to me once things shake out.
