That would depend on the sort of care these folks got, their rate of mortality, how the finances were handled, etc.Chicago Sun-Times reported:
"Barack Obama’s wife and three close advisers have been involved with a program at the University of Chicago Medical Center that steers patients who don’t have private insurance — primarily poor, black people — to other health care facilities."
This is known as patient dumping.
That's reason enough for a moderately intelligent and compassionate person to dislike Michelle.
Not saying she should get off scot-free, but I'm not willing to condemn her on that evidence.
