> all side activities are forbidden or made complicated

I know many places try to make this true, but not all do. If that is an issue that you consider to be a deal-breaker, then by all means, break the deal if they ask you to sign contracts that would stifle you.

> get high compensations

This isn't a priority for everyone. "high enough" is... enough. There certainly is a minimum that everyone needs. But lowering the expectations of your lifestyle means you can lower your compensation needs, and be picky about everything else. If the personal cost of gaining a 200K salary is too much... then it isn't worth the 200K you are receiving. You need to approach your salary as a business transaction -- you are giving up a chunk of your life and freedom in exchange for money. Be sure that exchange is a good match for you.
