Leftists keep telling the USA to look at Europe for guidance and they also generally support a wealth tax.
Okay, let's look to Europe.
In 1990, twelve European countries had a wealth tax. Now, only four have the tax.
Europe has abandoned the wealth tax because it doesn't work. It's nearly impossible to enforce and incredibly easy to avoid.
France, the latest country to abandon the tax, stated that the outward flow of wealth cost the French government twice as much as the revenue recieved by the tax.
A wealth tax only makes sense if your understanding of economics stops at your scribblings on the back of a napkin.
