We already had free health care for indigent people, even illegal aliens could walk into any community health care center and receive free health care. The only real effect I've noticed is a lot of people complaining about various aspects of the ACA.
This health care debate is nothing new, and has been in the works for at least 20 years. One could say that health care reform was inevitable, and would have been enacted in some form, or another, regardless of who the President happened to be at the time.
