Unfortunately it doesn't address the issue of how the poor, and much of the middle class, are to get medical service. The basic, underlying, irreduceable reality is that medical care is EXPENSIVE. No modern society will tolerate a situation in which some people drive Rolls' while others watch their children die of easily treatable, easily prevantable diseases because they can't afford to see a doctor.
Dealing with the poor is a problem for the gubmint, as they can't enforce any discipline on welfare recipients. For instance, drug use among the poor probably causes a signifigant part of their health problems, but the ACLU would wig out if we started mandating drug testing for them.
