On the first point, unemployment during the Great Depression was “only” 30%. And those people were eventually able to find other jobs. Here, we are talking about permanent unemployment for even larger numbers of people.
The Luddites were right. Machines did take their jobs. Those individuals who invested significantly in their craft were permanently disadvantaged. And those who fought against it were executed.
And on point 2, to be precise, a lack of jobs doesn’t mean a lack of problems. There are a ton of things society needs to have accomplished, and in a perfect world the guy who was automated out of packing Amazon boxes could open a daycare for low income parents. We just don’t have economic models to enable most of those things, and that’s only going to get worse.
