The most common issue raised by skeptics of wealth taxes is “capital flight”. As discussed in a Tax Notes article, “such a tax would signal to wealthy taxpayers that they should reside elsewhere.” This article goes on to discuss that high-income taxpayers pay the majority of state income taxes in California, and even if a small number of those individuals leave, it could lead to long-term tax collection consequences.
This concern has been underscored by numerous academic studies. Most recently, an NBER working paper co-authored by Jakobsen, Kleven, Kolsrud, Landais, and Munoz finds that 1 one percentage-point increase in the top wealth tax rate in Sweden and Denmark leads to an outward migration of wealthy taxpayers by two percent. Other work in the American Economic Review by Moretti and Wilson documents that variation in jurisdictional taxes significantly influences the location of talent, suggesting that higher tax burdens lead individuals to relocate.
The solution is to have a computer program draw congressional districts but neither party wants it because they like gerrymandering as long as it benefits it benefits their party.
