Oh but robots did create massive unemployment. Now there are millions, soon to be billions of people out of work, who can play tennis and soccer all day long.
Except they have no food, nor clothes, nor shelter. There are people called "owners" that keep all the food and clothes and shelter produced by the robots, unless you give them something they need in exchange. Which of course you cannot do, because there's nothing you have that they might need, not even your body—unless you are an attractive female, or they need one of your organs. There are already poor people selling their organs to buy food for their families.
That is quite simply what's wrong with the picture. Owners.
