TBF we are talking about unrealized gains. Their investments are worth more on paper, but until they sell them, the actual profit or loss will fluctuate. It would be an accounting nightmare to figure tax on unsold investments every year. I do, however, think capital gains should be taxed at the same rate as wage income.
