I can easily fire my asset manager, or switch to a plethora of low cost options, or manage my capital myself. How exactly will I have those options with the wealth tax if you like you said, I’m not getting that rate of return justifying the tax?
If you're a citizen of a country, you automatically get all of the benefits that come with it: personal safety, transportation networks, infrastructure, etc.—all things that enable your business to be successful. Since you can't opt out of these benefits (without leaving the country), it makes sense that you shouldn't be able to opt out of their cost.
