I'd compare the 2% tax to the average yearly gain in the stock market. Based on https://www.nerdwallet.com/article/investing/average-stock-m... it appears that the overage again is about 7% to 10% depending on how you figure it. The rule of thumb that I've heard in investing is 5%.
Therefore, my conclusion is that a 2% wealth tax on the ultra-wealthy on average wouldn't even keep them from gaining wealth; they would just increase their wealth more slowly.
