CA is imposing a tax on the TOTAL wealth of a person over the limits and excluding real property.
The Dutch impose a tax on the increased value of the wealth in the year, even if it was not "realized", which is more like our Capital Gains.
So an example, if you had Stocks worth 100 million, and they increased in value to 108 million in 2020
Dutch: 108-100: 8 million taxable, you owe $128,000
CA: 108 Million, you owe $432,000
Pretty large difference
and the Dutch Model is better in some ways when your assets DROP in value, which does happen,
so if we are in recession your stocks go from 100 million to 90 million, under the Dutch Model you would not owe taxes, under the CA model you still would
