I came across this animated explanation of why our economic future will be more and more bleak do to our diminishing energy and in particular petroleum resources. Making the whole right vs left paradigm rather moot.

 

So there you have. Unless someone,  somewhere manages to come up with a source of energy equivalent to or surpassing that of oil that is easily and economically obtainable – a feat the would require the research and development efforts of 2 world wars – we face an ever decreasing life style.
