Actually, there are plenty of parallels. So yes, if you only own the home you are living in, there should be a protection against taxation. Once you own more than the home you are living in, that property should be fully taxable, as far as property by itself is taxable (some countries don't have property taxes, other have small property taxes to exactly avoid the problems of this bill). With stocks it is the same. If you own a wide-range portfolio as an investment, this could be taxed of course, but with the people listed in the article, they own those shares not because they miraculously got rich and bought these shares with their money, they got the shares because they founded and built their respective companies. They hold to their shares not for capital gains, but to keep control of their companies. In this respect it is very much like the house you own. Not to mention the disruption to the stock market, if suddenly stock in the value several hundred of billions of dollars get sold - this would especially hit the non-billionaires, that is everyone who has some savings (for retirement for example).
