The Sanders wealth tax would raise some $4.35 trillion over a decade, according to the economists Emmanuel Saez and Gabriel Zucman, who previously found that Warren’s wealth tax would raise $2.75 trillion.
Zucman and Saez also delved into the 3 main differences between the Warren and Sanders proposals — Sanders would start the tax at a lower wealth level ($32 million, compared to Warren’s $50 million), and have separate thresholds for single filers and married couples.
Sanders also floated a national wealth registry to help in administering the tax.
