- Yes, I don't know exhaustively, but a number of countries with wealth taxes do not have gains taxes.
- Your comparison is a little bit mistaken, I think; you're looking at the tax only on the gain, whereas (obviously) the tax would be on the entire principle. I'm too lazy to do the math, but a wealth tax is easy to factor in, since it's a fixed reduction in total yield on wealth. The long-term historical return on capital in the west is about 4%/year; a 1% wealth tax is thus averaging about 25% of that. Gains taxes are typically lower than that amount. (Note that in the US the long-term gains tax is 20% at the upper bracket.)
