End the Capital Gains Tax??

The wealthy in this country already pay--as we've come to find out ala' Mitt "Mittens" Romney and Warren Buffet--less in taxes than the middle- and lower-classes. They pay in the range of a 15% rate--if that--while the rest of us pay more like 35% As if that's not bad enough, people have been calling for the end of the Capital Gains Tax? What? So they can pay even less? In the first place, shouldn't they pay MORE, comparatively, especially if you go by the Bible and our supposed Judeo-Christian values but even if you don't? Second, kill the Capital Gains Tax? As though we aren't already deeply in debt enough as it is, since George W. "Knuclehead" Bush got us into two wars, didn't pay for either AND handed out a huge tax cut for the wealthy already? Could we now kill even the possibility of ending this Capital Gains Tax idea? Please?
