That depends. Do you mean free market capitalism or crony capitalism?
To decide whether this is what free market capitalism intends, we'd have to determine if their wages are large due to free market forces (e.g supply and demand, etc) or if there is some government collusion going on inflating their wages.
CEOs pick board members, and board members decide their salaries. Further, board members tend to be other CEOs so it's in all of their interests to inflate CEO salary.
That would be the collusion, although I think it's less collusion, and more a misalignment of interests that lead to a negative outcome.
Because of the hysteria over "raiders" public companies have been able to prohibit shareholders from electing their own board slates, which has led to boards packed with insiders who collude to raise their and the CEO's compensation.
