They mention in the article that Amazon in Europe is largely unionized, and they don't have the mob. What makes you say we can't do the same here?
Is Amazon pulling out of the European market? Are the unions so onerous that it's unprofitable to do business there? Have there been massive waves of layoffs and replacing union workers in Europe with robots?
Yes, automation is coming, and yes society as a whole has to reckon with what it means to have an automated society with a drastically different labor market. But the fact that Amazon is energetically growing and pursuing business in Europe, proves what a strawman this whole idea is, that unions are somehow inherently ridiculous or could never possibly work.
Guess what, they're working, in production today, and have been for decades. The fact that entrenched powers don't want it to work in the US, doesn't mean it can't work.
Point being if you're going to make an aggressive claim of that type you'll have to back it up with evidence.
