I don't know if it's a culture thing or not, but if I'm paid low I expect I am being paid to do what I'm told, but if I'm paid high I expect that I am being paid for my expertise, and that includes advising the boss. (It's not about being obsessed with salary.)

None of this should be construed as a master/slave relationship.

For an analogy, if I go to McDonald's I am not interested in the opinions of the cashier, I just want to pay the money and get the burger. If I'm going to an expensive restaurant, I'm interested in the opinions of the waiter about what to order - that's part of what I'm paying for.
