He assumes the value of your shares don't increase : https://dqydj.com/stock-return-calculator/ https://dqydj.com/stock-return-calculator/ Let's assume you have $10k of AAPL shares and assume a 1% yearly tax on the value of your assets and go with this for a few years: start end value_after_tax tax_payed 20090120 10000 0 20090120 20100120 25842.79 258 20100120 20110120 39605.17 396 20110120 20120120 48493.94 489 20120120 20130120 59707.69 603 20130120 20140120 75046.31 758.04 If you do the above every year until today you have $528,254.27. With 0% wealth tax you'd have $592,361.08. So you basically payed an overall rate of ~11% without ever selling and paying capital gains tax. If the value of your investment is not going up by at least 1% every year then it's time to get rid of it, AAPL did have some bad negative years though. In any case, if such a tax gives us healthcare, education, housing, guarantees no one goes hungry, and a UBI for everyone then I'm all for it.
