Tax the shit out of these companies and use the money to fund more socially useful jobs in healthcare, caring for elderly people, writing code for public services and a million other things.

The fact that luxurious living wastes labour is not a plus for luxurious living. There are tons of things society could be doing with that labour that are more useful, they just don't get done because we allow pseudo-monopolies to retain too much rent.

I agree with that. But until that happens (if ever) I'd rather companies spread the $ around to their employees rather than keep it all for the shareholders.
