If I were to try to guess, it's that it forces political cooperation on people under threat of not having a job.
Imagine the situation where every single company in your state is a union shop (you have to join the union and pay dues if you work) - and every single union is wildly pro-gun, supporting candidates who want everyone to carry two guns (but they'll compromise to only men and only one if pushed).
So to live and work, your money has to go to support that. If you were anti-gun, you'd probably feel a bit annoyed.
