Man, you sure put a whole bunch of words in my mouth. All I'm saying is that unions are created in order to block change that they perceive to be in opposition to their interests. This applies to wages, automation and other things. This is literally what unions were and are created for. Police or otherwise. Are they good or bad? Depends. If you're in law enforcement, your employer is the government and you probably don't have a lot of choices of employer besides the government, so I'd say in that sector, it's a good thing to have. And the opposite for tech, where competition for workers drives wages and benefits up, and unions would only get in the way of that, and drain resources for their fancy offices. And last, not everybody lives in the US. I happen to live in a country whose growth and prosperity is directly hindered by unions who spend lavishly on offices and cars for their officials, but do very little for the rank and file, while stifling innovation, of course.
