Quick Summary

A California billionaire, Don Hankey, who left for Las Vegas shortly before the residency deadline for Proposition 40’s proposed wealth tax, criticizes the measure. According to a Stanford study, at least seven billionaires with combined assets of nearly $540 billion have already moved away from California due to fears over the proposed tax. Over 100 economists, including Nobel laureates and former White House economic advisers, warn in an open letter that the wealth tax is driving wealthy residents out, potentially harming the state's economy by reducing income tax revenue. They argue that implementing such a tax could lead to further capital flight and legal challenges.

Story summary

A California billionaire, Don Hankey, who specializes in real estate investments, insurance, and auto loans through his company the Hankey Group, has fled to Las Vegas weeks before a proposed wealth tax deadline. This move is part of a trend: at least seven billionaires with combined fortunes of nearly $540 billion—about 30% of California's billionaire wealth—are leaving the state due to the proposed tax, according to a recent Stanford study. Hankey told the California Post he left in December, before the January residency deadline for Proposition 40’s proposed billionaire tax, citing poor treatment and an unwelcoming attitude towards wealthy individuals. Over 100 leading economists, including four Nobel laureates and a former White House economic adviser, warn that such measures are driving the rich out of California, potentially sacrificing years of income tax revenue.
