 This will kill the stock market because if they tax you on some of the stocks you hold that you're not planning on selling, you're going to have to sell some of that stock to pay the taxes on the stock you didn't plan on selling. This is a game they're playing, and it's a game with your wallet, and it's a game with your financial future, and it's not fair. If people have built money up, they shouldn't have to pay tax on that money.
