100% unskilled labor can't successfully unionize anymore. In the old days they had the mob and strategic use of violence to force the Union into a position of power but that is no longer possible.
It's a rather pathetic threat to make. Either it happens or it doesnt - unionization won't make automation technology intrinsically better.
Shouldn't it be the other way around? Businesses have to invest more in productivity to maintain their profitability, thereby increasing the capital's share of profits because they need to pay for the capital?
You are not making any sense. If it's all so great in AI robotics land, it would be here already.
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.
If you don’t Amazon treats you as expendable, if you do, you will only accelerate automation further resulting in fewer unskilled jobs.
To be fair, that could backfire as well. There seems to be some anti-big-tech sentiment floating around in the US Congress right now.
