If the wealth tax rate is close to zero, who the hell cares?
The wealth tax in e.g. Kanton Zürich is 0.025% (not the cheapest Kanton).
If you are able to grow your capital at - say - inflation corrected 4%, which shouldn't be overly hard, and you pay no taxes whatsoever on cap gains while paying 0.025% on the total accumulated wealth.
I'll let you do the math as to how good you have it there.
If you now earn 4% on your capital and pay 0.9% wealth taxes that is like a 25% tax rate on your unrealized gains. Inflation is close to zero anyway and interest rates are negative.
Obviously I prefer that system because we can compound essentially tax free to a couple of 100k before having to think about taxes.
Real estate is included in that wealth, of course. And it has a different tax treatment than "usual" stock market gains.
