This is also a pipe-dream. You can't automate plumbing, drywalling, framing and dozens of other construction jobs. They already can't find people to work those jobs - when you add UBI do you think there will be more of those workers? No. So who's going to build the houses? Who's going to make the supplies? Who's going to pick up trash? Moreover, who's going to be a nursing assistant, a home care aid, or even a teacher?
Your response is smug and glib. You can make 150k without too much trouble as a plumber. Or a mason. And still they can't find people. If you can't find people to work for those wages now, you think UBI will make it better? Please do explain that to me.
There are plenty of people who might still think that's bad value. Trades put a lot of stress on your body, and are not that easy, especially masonry from what I've heard.
If you think of people working in the service sector, like fast food, or retail, I don't think most of them would cut it as a mason.
Aside from that anyone who has a way to make similar money another way would probably do so instead, I certainly would.
>You can make 150k without too much trouble as a plumber.
So my 20 second research shows the average salary for a plumber is around $50,000, with 90% making under $75,000. I bet more would be willing to be a plumber for the kind of money you mention, but that's not standard.
Fewer workers. That's the whole point.
For years, companies have been investing billions into automation and efficiency improvements. Less and less humans are required to do the same work.
Of course, we aren't at 0 yet, but it's trending lower and lower. It doesn't take doubling a human workforce to double output anymore.
