>whose output remains the same This is irrelevant, though. You aren't paid based on your output, you're paid based on how much you cost. Think of how much you pay for water. In place A, you might pay $0.02 per gallon of water. You move to place B, and they only charge $0.01 gallon of water. Are you going to keep paying $0.02/gallon? The value that the water provides to you hasn't changed, but why would you keep paying $0.02 when you could get it for $0.01? In FB's view, you aren't any different. Even if you provide the same value, there's no reason to keep paying you $300k when they could pay you (or someone who replaces you) $150k.
