hammer at the root cause

after some stage of economic stabilisation the root cause of original tumble of economy stares in front of americans (i suppose).that is disproportional rise in gas prices.

in fact that has harmed detroit, and banks and then housing industry.

americans will have to do now what they have to do that is hammer at the root cause of gas price rise.

what are the options? first and foremost is compressed natural gas which is burned off now and is dirt cheap. if at least 50% of americans use cng for transportation then it will have thumping impact on oil market in middle east and saudi etc. in fact for next decade americans will be able to dictate market of gas (dream situation).americans can make a start at urban transport immmediately.

secondly. well i do not see second option, (unless hydrogen is used as fuel.)
