I don't think an individuals healthcare is the responsibility of society.
And we're never going to "run out of fossil fuels", it will eventually become to expensive to get out of the ground what it's worth on the open market, but we'll never "run out". The market will take care of the rest (unless the govt farks it up with ethanol subsidies and other "hand of govt" manipulations of the market).
This statement is almost comical. You assume that the best interest of those who dominate the market to be the same as the best interest of America. A transition to a non-fossil-fuel economy will take many years of reserach, infrastructural preperation, and a change of consumer culture. It is not something that can happen overnight once fossil fuels become infeasible. Furthermore, why wait to hit that crunch period where fossil fuels become unbearably expensive? It will not occur in a matter a months but will be a prolonged period of several years of recession and likely stagflation. Wouldn't it be better to avoid this entirely (as well as combat the problems it already causes to our national economy) through a proactive national effort right now?
