Valuing productivity is already reducing U.S. inequality. Lawyers and doctors can’t prevent people from getting better educated nor can they completely bar technological advances. Sure they can take short-term measures like regulating DNA or law-tech companies, etc. But many people have an inherent desire to get higher quality health and legal help for cheaper. Regulators can’t and won’t ever completely stop the decentralization movement.
I live in rural USA. State boundaries do bring our town together with the major city in our state, the problem is their voice drowns ours out. Wouldn’t more people be represented if we started splitting up states? Wouldn’t we all be better off from less monopolized regions?
