Yes, cash for service will increase, absolutely. In some ways it already is with the so-called "minute clinics", this will expand into private medical treatment and perhaps even some traveling docs. But the government will move in to control it, you watch! They'll blather on and on using words like "public safety", "unregulated/Unlicensed", "back-alley", "law-dodging" & "tax-dodging" and look to kill or regulate it.
Thew more they squeeze the more it will go underground, and then the cost for this will eventually go up, so in the end the future is dim for average Americans.
Best solution is widespread and overt non-compliance and defiance...make the state show its fist, then we'll see where this all goes!
