It's called income tax, which isn't new, and used to be much higher for the top brackets. Income tax rates are not derived from the Constitution, and an amendment is not necessary. But if someone wanted to propose an amendment to forbid taxation, then good luck to them.

Let's say a group of 3 people wanted to pay for something that costs $3k. They want to split the cost fairly, but two of them only own $1k. The third person owns $70 billion. Would you ask them to agree to each give $1k? Or would you ask the person with $70 billion to maybe cover, idk, at least half? Anyone that answers "well its not fair to the person with 70 billion to ask that they pay more", is an idealogically-captured simpleton. It only takes basic logic and empathy to derive the obvious answer but meaningless ideology prevails somehow
