If it happens the way I am expecting and I make more than a million, I will do everything in my power to hold longer than a year, consequently avoiding this 15% penalty (if in fact it exists, I am not sure about it).
I already contribute too much to uncle Sam's wealthiness. In my opinion, 25-30% is a fair number - 45% would be pretty much cutting my profit in half. And believe me: uncle Sam hasn't helped me on this one. This is only based on my decisions and the awesome DD of this board (thank you all who contributed again).
Amazing seeing people in Belgium, for example: tax is ZERO!
