I see where you're heading, but I think this is an odd comment. From a market perspective, the few big companies can afford to pay really high wages because of a monopoly-like situation that they are under investigation for, while still having profit margins that would be deemed absurd in more competitive businesses, like the car business. The lack of competition is hurting the rest of society. The way you keep your employees is by making sure they're treated well. This includes, but is in no way limited to, salary. Unions are a solution to not being treated well. Hiring someone is a bit like marrying them, IMHO. Maybe I'm an outlier.
