Today I learned about an initiative for citizens of the European Union (not Switzerland, not the UK, sigh) which seems to have just the right name: Tax The Rich!
https://www.tax-the-rich.eu/

Found that via an article of the @tazgetroete about taxing the rich (German): https://taz.de/Vorschlag-zur-Soli-Abschaffung/!5987569/

The part that I don't get is that they mention how Switzerland taxes the rich but from my point of view, the tax is minuscule (and it depends on the canton, of course): In 2018, Geneva was at the top with 10.1‰ and Nidwalden was at the bottom with 1.3‰.

Nidwalden is one of those mini-cantons. Within a tiny country of tax-evasion profiteering there is a tiny canton of tax-evasion profiteering. Well, several of them but this is one of them.

And of course with the global minimum tax efforts, those tiny tax evasion cantons have to switch track: from low taxes to company subsidies.
