Hey, sorry for not replying in a timely manner. I made the comment above and then was dragged by work for the last 3 days, and completely forgot about this.
I got a lot of good other comments, but the reason I'm replying to you is this: You miss understood what I said. (My bad?)
I was not saying that unions are good, or that unions are bad.
I was just stating how contradictory the opinion on unions is on the US. A large % of people think that unions are bad, but they accept as a matter of fact that police unions exists.
The fact that _they_ exists, means - IMO - that their associates get benefits from that, more often than not, considering how widespread police unions are.
I don't think that unions are inherently bad or good; I think that depends on the culture of the country.
In my country, almost everybody is in a union, and they do a general good job of fighting for salary increases on a yearly basis.
The downside of unions here, is that the truck drivers unions have lobbied extensively over the years against new rail roads, and that goes against the well being of the general population.
I follow a "UK Legal Advice" subreddit [1] (I don't live in the UK, but I work for a company there" and more often than not the advice given there is "Adhere to a union". Basically, unions good / bad depends on the country.
