+1 on the point about movie-star and athlete unions. And as you said, the descriptions of unions are pretty cartoonish and portrayed as universally undemocratically accountable to their members.

What I find even more remarkable about the "too much self-interest to form an effective union" based argument is that highly competitive companies in every sector routinely find common cause and form lobbies to influence policy to benefit all competing members within the lobby. Somehow, this phenomenon does not seem as mysterious to the public as scientific labor finding common cause to form a collective of any sort. So even the idea that self-interest in general precludes solidarity is untrue. As for points of specific tactics, different unions have tactics other than strikes. I mistakenly assumed this point is self-evident to folks but perhaps it is not. And the assumption that HN commenters are unaware that scientific work also goes on in other countries independent of any union intervention in the US is...incredible.

The point raised about being scooped while on strike (or that one's career will suffer while others continue to work) is identical to one of the explicit anti-union campaign talking points raised by U Penn a couple of years ago. I was pretty surprised to see such an identical point show up on here.
