All fair points, but even within the US, $5m goes as far in some states as $50m does in some cities. Besides that, one person's "personal safety net and toys" is another person's "not enough", is another person's "greed".
Meanwhile, you're getting taxed on the estate you're trying to build as you build it.
Twice.
Every year.
As someone who's currently attempting to build his own personal empire, I'm incredibly glad I don't have a wealth tax to contend with. It's hard enough as it is, without knowing that if I start to draw close, it'll get harder and harder as I go. I might not have started trying if it didn't seem possible in the first place. Then again, I might have done it anyway. Where's a quantum theorist when you need one?
It seems it would have the effect of magnifying down markets. (Down 30% in the market? Pay us another 1.2%, please, selling shares if you must; we don't care.)
Over the course of your life, the government will get more of your wealth that you (or those you designate) will. (At 5% CAGR, the government is ahead by year 54. At 3% CAGR, they're ahead at year 56. At 8%, year 52.)
That's assuming you stop earning, but of course most people will not stop earning. Also, the typical way this works is that the wealth tax gets added to your income, so if you end up not paying income tax by definition you don't pay wealth tax.
Example: Say I'm worth 1M credits today and my wealth tax is 10K (1%), that means my income gets another 10K added to it. Real income is 50K, + 10K so I pay tax as if I earned 60K. 40% of that works out to 24K worth of taxes.
In a bad year I'd earn maybe 10K, add that 10K (I'm still worth that 1M), and that year would pay 40% of 20K, which works out to about 8K.
Progressive tax scales can further improve the situation in years with low income.
The markets don't have much to do with this, it's a fictive income, not what you actually made.
Good point, I was making an assumption that this was a wholesale replacement scenario for income and other taxes.
My only other quibble is that I haven't seen healthcare costs or insurance premiums scale to that 10x factor like housing prices do rural-vs-urban, otherwise I'd personally be perfectly happy with moving and retiring early. Get the right cancer or nasty chronic condition and you're gonna be out some serious bucks.
