What I worry about most with a wealth tax is calculating your wealth. Income tax is already hard enough. Now start adding up the value of your stock, your real estate, your personal property, etc.
And are you committing tax fraud because you have a million dollar painting that was hanging on your parents wall for decades that you inherited and never realized was valuable? Are you committing tax fraud if you have some crypto currency that you forgot about that has skyrocketed in value? If not, then these things can be used as tax dodges by the wealthy. If so, then it just makes everybody a potential criminal.
