Completely ignores the true distinction between wealth and income taxes.

Person A has one billion dollars. Holds it in cash in a vault deep in a mountain he owns. He does not earn any wages.[1]

20% income tax: $0.00

01% wealth tax: $10,000,000.00

[1] Every billionaire controls their taxable income. Unlike wage earners, billionaires have 100% control over how much taxable income they have each year. They make choices.

They can have the vault in the cave. Or they can put money into artwork that grows in value and only generates income upon sale. Or a million other ways they can choose to control taxable income.
