He said that only to establish a power relationship because that was how that company worked.

Well, establishing a relationship of respect and power is part of management, but there's absolutely no reason one needs to be a dick to do that.

That sucks, sorry to hear it. Maybe it's a sign of the times (I've only been in the industry about a year), or just the managers I've been fortunate to work under, but in my experience, coders always get more respect than to be bullshitted like that. It all comes down to money, I think:

If the company pays you less money than the wealth you generate, and provides good enough benefits/environment, you're playing a win/win game where everyone's happy. Yes, there are times when your interests diverge - your manager has a budget to minimize and you have a family to support, but those are exceptions to the rule.
