I'm assuming everyone who makes under 40-50k a year gets a subsidized plan and price. They're gonna aim for 20-25% of what you make, up to a certain amount, fed taxes will be 25-30% with lots of the old deductions gone, and state and local will be 10-15%. So you can keep 30% or so for your self.
The ones who are advocates of this, and really will gain are those making 20k a year or less, or not working at all. These folks can get lots more subsidized stuff. The truly rich won't really be hurt much by obamacare. the middle class and upper middle will be the ones who really see these new taxes and obamacare hit hard. Its soon gonna be very difficult to be middle class as obamacare forces all to be poor and on the dole, or one of those above it all, the middle will be taxed out. Its not by accident. J
