Are you sure the Harris proposal is only about publicly traded stock portfolios? Maybe I'm missing something, but I don't see publicly traded stocks being singled out by the President, which is supposedly the policy Harris is adopting.
"The proposal would impose a minimum tax of 25 percent on total income, generally inclusive of unrealized capital gains, for all taxpayers with wealth (that is, the difference obtained by subtracting liabilities from assets) greater than $100 million."
And there are many private farms in America worth more than $100m. I have no idea what amount of that would be "unrealized capital gains", which is kinda the problem.
