What we're actually missing is any party that hasn't been completely pwnt by corporations. If you take a look at this proposed law, it explicitly excepts hedge funds and the like. Yet again the authoritarian ratchet will click for individuals while corporations escape regulation, leaving them even more powerful. The hypocrisy is blinding when you really dig into the mechanics of tax law - individuals have to pay taxes on their expenses of shelter, transportation, food, whereas if the same situation were interpreted as a business those would all be deductible as expenses necessary to earn income.
What if instead we flipped the paradigm such that if you want a government granted charter to create a liability limiting entity, that is what gets heavily taxed while individuals would get left alone for the most part. Require bookkeeping only from the entities that live on it, rather than forcing the yoke onto human beings. Applying this to income-distributing trusts as well would go a long way towards fixing dynastic wealth, without even touching the estate tax.
And tangentially the right thing to do about the massive paper gains of the stonk market over the past nineteen months months is to call in all those loans made by the Fed by raising interest rates back to a reasonable level. But that would stop the fake riches gravy train and hamper trickle-up wealth redistribution, so corporatist policy will continue to carry the day while individuals get squeezed by the resulting increased financialization.
