Abortion is morally bad, sure, but do we really want 1 million more lower class children per year?
As far as what is done with the fetuses after, I'm not sure why anyone really cares. At that point they're dead. Who cares what happens to them after they're dead... they're DEAD. I can tell you who doesn't care what happens to a dead body... the dead person. Because they're DEAD. Hell, an argument can be made that aborted fetuses weren't even alive to begin with. Might as well make some medical progress and allow them to provide utility to society instead of just being waste.
