In the only countries that still have a ‘wealth tax’, the thresholds are so broad that they are primarily a burden of the middle and lower classes, making it effectively no different than a more conventional/mundane tax, versus what everyone talking about a “wealth tax” in these kinds of discussions invariably expects; namely, a tax that only/primarily targets the wealthiest.
Before the income tax was implemented, there were promises it’d only be aimed at the rich, too.
