Ridiculous overreach. Perhaps if you really want a wealth tax, take a look at existing systems like Norway and Switzerland and suggest something along those lines. The percentages are in the 0.5-1.5% range.
If you had gotten $10,000 just once 80000 years ago and invested it into a low-risk fund with a 0.5% profit, you would have approx $5.6 * 10177. Which is about $5.6 * 100165 more wealth than Elon Musk has.
Perhaps the Ron Paul of DemSoc should give space to newer generations.
