I think the whore analogy is correct, but not in the way it was put by payraise. How many whores want to be whores? I imagine that they are in that situation because they have exhausted all possible other options to survive.
That is the point c150 is trying to make.
Being a whore is OK if you have no choice. It even has a certain dignity to it if the intent is to get back on one's feet, or support a family doing the only thing that one is qualified to do. - But how many people leave good jobs to become hookers?
Don't be fooled into thinking that the unions are always on side with ALL the pilots either. The unions are nearly always run by the more senior pilots, and during negotiations when the temptation comes to trade layoffs for better pay and conditions, the senior guys can figure out which side their bread is buttered.
