What is your end goal of taxing wealth? If it is to "pay for" social programs and benefits your efforts are less than effective, and are actually counterproductive because they feed into the false concept of limited money available to spend on the public purpose and put that goal in direct opposition to the most well funded and politically connected people in America. It also frames the debate in the language of the "enemy", in this case those who would pay the tax.

Congress, as the monopoly issuer of our sovereign fiat currency, has an infinite amount of dollars to spend on whatever it can agree as worthy. It has never been revenue restrained and there is "NO" correlation between such revenue and its ability to purchase whatever resources exist and are denominated in the dollars it creates at will.

In other words, if there is a need for dollars in the private sector to fund the "common welfare" it is mandated by the Constitution that Congress provide that funding, full stop. No taxation or borrowing is necessary. The concept of "needing" the money of the wealthy to achieve the public purpose is only a dodge that our corrupt Congress uses to keep labor subservient to capital. If society needs better healthcare, education, infrastructure it is only because Congress doesn't want us to have them, not a shortage of "funding".

The best hope you have of making the wealthy pay more, which they should, is to make them irrelevant, which is the opposite of what you are proposing.
