Overhead will eat you alive if not constantly viewed as a parasite to be exterminated. Never mind the bleating of those you employ. Hold out until mutiny is imminent before employing even a single additional member of staff. More startups are wrecked by overstaffing than by any other cause, bar failure to monitor cash flow.
You shouldn't go around the world behaving ruthlessly when you don't have to. Sometimes you do have to. There is only so much pie to go around. If you're going to take more than your fair share of pie, as socialists would look at it, then someone else is not getting his. That means you've got to take it away from them.
