The centerpiece of Elizabeth Warren’s and Bernie Sanders’s presidential campaigns is Medicare for All, which each senator has said they plan to pay for through a wealth tax on the richest Americans. Some people, who believe both that the United States should have universal health care and that the 0.000001% is a scourge on society, are very much in favor of these proposals and the mechanisms to finance them. Others, like Hillary Clinton, are less enthused.

Appearing at the New York Times DealBook conference on Wednesday, the 2016 candidate called the wealth taxes “unworkable” and warned that they would be “incredibly disruptive” if enacted. (Warren’s proposal, dubbed the “Ultra-Millionaire Tax,” would impose a tax of 2% on American households’ net worths between $50 million and $1 billion, and 3% on those above $1 billion; Sanders’s tax would start at 1% for household net worths of more than $32 million and gradually increase to 8% for couples worth more than $10 billion.) Arguing that it would be too difficult to accurately evaluate Americans’ net worths, and would force people to sell assets like stocks to pay the taxes, Clinton said she “just [doesn’t] understand how that could work, and I don’t see other examples anywhere else in the world where it has actually worked over a long period of time.... If you were going to do a wealth tax and it was on assets...how you would value it is, I think, complicated to start with. But assume you can get some system of evaluation, people would literally have to sell assets to pay the tax on the assets that they owned before the wealth tax was levied. That would be incredibly disruptive, so I think there are other ways to raise the revenues.”

On the other hand, Clinton said she’s “all in favor” of reinstating the estate tax, which Republicans effectively eliminated with their 2017 “middle-class” tax law. Sanders wants to tax the estates of Americans who inherit more than $3.5 million, impose a 55% rate on estates worth more than $50 million, and make the top estate tax rate 77%. Warren has floated a similar proposal, which she says would cover the costs of more affordable housing.

Neither Warren nor Sanders appears to have responded to Clinton’s comments, though it’s not clear the progressives will be too broken up about the criticism. As Wall Street has lost its collective mind over Warren’s proposals of late, the senator has responded by...campaigning off of their hysteria:
