No, it's not; income limits are set by states, vary by population, and for populations that are covered at all tend to be much greater than $20/mo. The Medicaid expansion as part of the ACA also resultted in substantial changes in many states.

I'm questioning whether entitlements really help rebuild that solid ground for rural Americans in economic hardships.
However, until scarcity is totally eliminated, we'll be faced with the same challenge over and over again - how to bring prosperity to those whose roles in the social and economic order have been eliminated.
I have no good answers.
Moving to where there is economic activity is what many rural Americans need; identifying the fruitful places for that for one's individual circumstances and executing the moves, however, is harder to do when you can't meet subsistence needs, and sometimes people are going to need retraining to have new opportunities, or simply be past the point of having new opportunities, requiring additional individual support.
