Well aside from what I already mentioned, it's possible for the manufacturing of consent against socialized medicine to be halted out of fear leading to M4A finally being adopted. It's possible that this will lead to non-violent protests that agitate for change. Certain politicians might be able to leverage this in the near future to get a bill passed. It could happen that it'll lead to a sudden increase in community aid and health facilities accommodating such.

I'm not saying what is and isn't likely to happen, all I'm saying is that we don't know. Anyone who thinks they know what will happen is an idiot or a liar, possibly both.
