Whenever I bring up the idea of taxing the rich via unrealized gains, people oppose it by saying it’ll hurt investment. The reality is that years of huge stock market returns haven’t made life easier for the vast majority of people who actually do the work that makes companies successful. At least in the US, wages haven’t kept up with housing, healthcare, or basic costs, and I’m sure European workers face these kinds of problems too. At some point, it’s fair to ask why protecting unlimited tax-free growth for the top 0.1% should matter more than the financial stability of the workers actually doing the hard work to drive that growth. If the Netherlands finds that people avoid taxes by investing into real estate rentals, then maybe there should be laws covering those loopholes too.
