> In 1990, about a dozen European countries had a wealth tax, but by 2019, all but four had eliminated the tax because of the difficulties and costs associated with both design and enforcement. Belgium, Norway, Spain, and Switzerland are the countries that raised revenue from net wealth taxes on individuals in 2019 with net wealth taxes accounting for 1.1% of overall tax revenues in Norway, 0.55% in Spain, and 3.6% in Switzerland for 2017.
The citation for those statements links back to the OECD, so they apparently don't count the Italian and Dutch taxes as "wealth taxes". The NPR transcript linked elsewhere says only three countries have it, so that interviewee may not be counting Belgium either (since the tax is solely on financial instruments and not total wealth).
