ACA addresses major cost drivers in an attempt to bend the curve of what appears to be inherent rising costs. The benefit would be universal, not simply for the individual and family but for business and the economy.
The free market failed to address this problem. ( and all those rejoinders about tort or more competition are nothing but smokey mirrors meant to deceive the weak minded, none of those can bend the cost drivers). The main reason no conservative talks about alternatives is because there are no alternatives.
