There is a real problem when huge amounts of US consumer spending is being funneled through tax advantaged entities in order obtain near zero effective tax rates for people who measure profit in billions.
The tax code is 100% a tool for the mega rich to competitively cheat the US consumer. There are other things like regulatory capture, monopolist practices, and accounting fictions.
The abuses are absolutely ridiculous.
However, the voting citizens of the United States have started to wise up.
Up until now they have been placated with excuses, lip service, misdirection, outright obfuscation and various other forms of denial.
A wealth tax may be clumsy, and it may be unsophisticated. It may even be ineffective, but the people of the United States know the game is rigged. They just don't really understand who is responsible. They suspect that there is blame among all of the moneyed class.
But, believe me, the middle class is getting bent over every day of their lives and they are starting to wonder whether it is worth it to sit by and stay quiet when Warren is saying let's even the score. There is massive social unrest in this country. It is a tinderbox.
The US government has a massively inefficient record at tax enforcement. But likewise it has a terrible healthcare regime.
There's no need to hand the country over to Socialists because of some poorly framed policies that were inevitably poorly enforced. Once they have the US, its never coming back.
