Can someone verify this answer? I don't feel like it even answers the question. Where does the 23.8% tax on capital gains come from? I thought capital gains were taxable to 50%. The answer shows the amount of tax that would be paid, but doesn't relate this specifically to income....and as the comment states, the last answer should be a loss.
