Let's play the rich get everything. The rules are the rich get everything. participation is mandatory.
Did I say mandatory? I meant optional! You're "free" to die in a cardboard box under a freeway as a market capitalist scarecrow warning to the other ants so they keep showing up to make us more!
The tax rate during the New Deal (which corresponded with the largest jump in GDP and middle class growth) on people earning $200k and over (now would be like earning $2.5 million/year) was 95%.
During the 50's through the early 80's, that tax on the wealthiest was at 70%.
Now it's at 37%, less than half of what it was during the best years of growth our country ever experienced.
Additionally, you'd only pay taxes on unrealized capital gains if at least 80% of your wealth is in tradeable assets (i.e., not shares of private startups or real estate). One caveat is that there would be a deferred tax of up to 10% on unrealized capital gains upon exit.
In short, it would not apply to most startup founders or investors, but would impact top hedge fund managers.
