That's the entire point of it all. I think you are the only person in this thread who gets it. When there isn't a labour force available, you have to increase salaries to get workers. This means other industries and businesses have to increase salaries to keep their workers, giving a domino effect – meaning higher salaries for workers across the board. It might even mean that shit industries can't find any workers and have to close shop. For example the restaurant industry.

This also means higher prices across the board for consumer goods, but the worker still net benefits greatly.

Who does not benefit: The people who do not work. And that's fine. But it's also this class of people who make the entire political and media class, and hacker class apparently, so that's why we have this enormous resistance.
