Yang vs. Warren: Who Has the Better Tax Plan?
In the race for the Democratic presidential nomination, Senator Elizabeth Warren, of Massachusetts, and Andrew Yang, a former tech executive and entrepreneur, have both proposed bold plans for redistributing economic resources.

Their plans are as different as can be. Only Mr. Yang’s is practical.
This article doesn't even talk about Yang's plan, but it's a good overview of why wealth taxes are such an impractical idea. This seems like it should be obvious to anyone paying attention to history: most of the European countries that used to have wealth taxes have gotten rid of them. The VAT, on the other hand, is now used in basically every country other than the USA.
