This reminds me of the idea that taxing corporations does nothing, because they just shift the costs to customers…so apparently companies fight that tooth and nail not out of self-interest, but pure generous concern for them.
I mean, you can’t get more rent from someone who has spent their new money on food, but at least they’re not hungry. It’s not hard to tell if higher wages just shift wealth to different exploiters or manage to improve people’s lives. Some places have minimum levels higher than others, and I think it is not hard to establish that on average people in them do better.
