The Math Behind the Billionaire Tax Debate
We agree on the goal. Let's be honest about the method.
Those who benefit most from society's infrastructure should contribute more. But good policy requires honest math. This tool shows what Zucman's proposal actually means.
Old money. New money. Dead money.
Old Money
Inherited, generational, quiet. Lives in estates and trust funds.
New Money
Earned, first generation, loud. Lives in startups and headlines.
Dead Money
Wealth so large it will never be spent, enjoyed, or deployed. Just score.
Piketty showed us the mechanics. Zucman showed us the math. Neither asks the obvious question: Why would anyone want wealth they can never spend?
A 2,400-Year Conversation
In a state which is desirous of being saved from the greatest of all plagues... there should exist among the citizens neither extreme poverty, nor, again, excess of wealth.

Plato proposed that no citizen be more than 4× richer than the poorest.

Today's ratio between Elon Musk and the median American: ~1,000,000:1
The question isn't WHETHER to address extreme wealth concentration. It's HOW, and whether we're honest about what we're actually proposing.
Our Position
Wealthy individuals have benefited enormously from society's infrastructure: roads, courts, police, educated workers, stable markets. They can afford to contribute more, and they should.
But...
Good policy requires honest math. When proposals layer new taxes on existing ones without disclosure, that's not progressivism. It's sleight of hand.
We're not defending billionaires. We're demanding transparency so the debate can be productive.
Three Key Insights
The Double-Dip Problem
Zucman proposes 2% annually but never mentions that these individuals will ALSO pay 40-45% estate tax at death. That's not oversight. It's omission.
The NPV Question
When money arrives matters. Annual payments now are worth more than estate taxes in 20 years. A fair comparison requires present-value analysis.
What's the 'Fair' Rate?
We calculate the NPV-equivalent annual rate that matches estate taxes alone. Spoiler: it's about 2.3-2.5%. Zucman's 2% is actually LESS in present value terms, before you even add estate taxes. That range assumes a 3% discount rate. It falls as the discount rate rises: 2.00% at 4.25%, and 1.79% at 5.25%.
A Better Approach
Instead of double-dipping, what if wealthy individuals could voluntarily accelerate their estate tax obligations?
The Mellani Proposal proposes exactly this: prepay now, get credit later. Government gets money sooner (higher NPV). Taxpayer avoids double taxation. Everyone wins.
