Does this worker have more, or less, money than before? It's not a matter of opinion. The answer is less, and we know that's the answer because that's specifically what you're seeking out.
What you're arguing is if this harm is justified. Maybe, maybe not. In your opinion, it is. My opinion is that the marginal effects of me not tipping will have zero impact on the culture, so, for now, I play by the rules. The rules are stupid, I agree, but I still play by them.
You are, and it's objective.
