Court House - I see that the Democrat senator from Oregon is proposing a tax on un-realized capital gains. That means if you have an investment that increased in value over the last tax year, you would have to pay tax on that gain, even if you still hold the investment, and haven't sold it (as it is now). This also means that if your house, business, car, collectibles, etc. goes up in value during the year, you'll have to pay the tax on the difference as well. This is an unworkable idea.
