This comment is much more revealing about you than I think you realise, but it's good to know at least that there's no point in wasting time on arguing things on the merits.
Fearmongering and/or hand wringing about what could get worse in the future doesn't change that reality today.
The big risk to a worker is that they overestimate their skill level, which absolutely does happen, but those people are not in the above average pool I'm talking about in the first place and would in fact benefit from a union.
