Yeah, but they don’t benefit from public health services, since they can pay for a private insurance with a higher quality of services. They don’t benefit from social benefits, since they have much more efficient ways of making money. They don’t benefit from public schools personally, since they can send their children to private schools. So if I were to go with the reasoning that people should pay for received services proportionally to the benefit they get from them, I don’t think we’d end up with a system where the rich support the poor better. That’s all because the needs of the poor are very different from the needs of the rich.
