I don't necessarily disagree with any of your arguments. I have good working conditions, yes. My wife has good working conditions; she's forced to be in a union at her current job, but in previous jobs doing the same work, she was not. She doesn't like them, either, but again, we're both professionals.

However, your reply is structured around trying to convince me that I should be pro-union rather than ambivalent, and does not address the issue at hand; how to square "right to work" laws and the free rider problem with unions.
