Legalization started with two small states; it currently generates $3.75B/year in states representing about a third of the country. Notably, New York legalized sales on December 29, 2022, which was too late to generate significant tax

This is what my family did in the '90s. In the beginning, it was easy: we handed the teachers a note and we were on our way. As I got older, the school was less cooperative, and focused on boosting attendance statistics. The ability of

I believe it could also be argued that some fraction of the value created by repairability is in fact an externality. Your standard rational pricing model uses exponential discounting. A farmer does not necessarily expect to be in business

Such a reduction is known to exist, but that doesn't mean it's necessarily easy to implement. It would suffice to find some large instances of 2-maxsat and solve those.

A major argument for income tax is that it's naturally countercyclical, which means that governments tax more when incomes are high and less when they are low. The 'progressive' — concave upwards — income tax is even more so.
