@djc how should we tax in this kind of world? can we even make claims about who is rich or poor based on income or wealth? what are my incentives to work, if getting to a higher paying job just means the stuff i enjoy today gets more expensive? maybe there are answers to all these kinds of questions, a worldview under which we can make sense of distributional outcomes despite pervasive price discrimination. but i don’t know or understand it. 10/
