I think the 80% thing you&#x27;re discussing is a bit like the &#x27;duplo economy&#x27; that PG mentions in his essay. Very large broad-brush taxation, with little specificity.<p>It would be trivial to make the taxation regime more high-resolution so that people who reinvest their cash into other ventures are taxed at a far lower rate, whereas those who wish to retire early and do nothing else are taxed a lot more.<p>Better to start from the society you want to see and work backwards from there to design a taxation system, rather that say yes or no to one or two one-size-fits-all options, I think.
