So similar to current situation in many places - if you are rich enough, you basically exist outside of tax system, be it capital gains, investments, inheritance etc. Obscure tax structures spanning whole globe as ie Panama papers showed. Its the middle class that gets hammered out of existence, ie in France its around 40% for inheritance tax, and trusts are AFAIK forbidden / treated very punitively. Very rich still bypass this and everybody knows this, everybody below not so much. Its not even effective there, the amount extracted yearly in such way is minuscule, but it pleases crowds with 'social justice' so they don't protest so much and burn more cars on streets.
