Perhaps this is just my perception, but I would say the difference is that European unions (at least northern European, can't speak to the rest of Europe) seem less inclined to engage in dodgy behaviour than their US counterparts. I'm specifically thinking about construction, ports, etc.

I mean the fact that there are people employed to literally do nothing, "because that job used to exist and must never go away" is one example of this. It's not something I've heard of happening in Europe to the same extent it seems to in the US.
