I'm not a libtard, ...but in answer to your question:
This is how the economy is to blame for high gas prices.
The US dollar is worth less today, than it was in 2008. Simple.When Obama took office, gas was $1.83 /gallon (183 units of American currency)
Today, gas is over $4.00 /gallon. It requires more units of currency to acquire the same thing.
Remember Sept 2008 when the stock market crashed? ...and the Bush administration injected all that money into the economy? Printing and injecting all that money devalued the dollar, so now it requires more dollars to get the same things because the dollars are worth LESS and LESS each day.
Now with Fed chair Bernanke's announcement of QE3 to infinity at a rate of at least $40 Billion per month, the dollar will become worth less and less and even less with each passing day.
Between 2001 - 2011, I have earned my income in US Dollars, and I've seen the steady devaluation and obliteration of the USD every week when paycheques arrived. Every week I would see the narrowing spread between the 2, as the conversion rates from US$ to CDN$ shrank & shrank.
In the last 4 yrs the US$ has lost over 42% of it's value to the point where it is worth less than the CDN$ and worth less than even the Australian$.
Nowadays I don't trust any fiat paper currency. Unfortunately life is such that we still require paper money to function (for now), ...so these days, I make sure my income is paid in a combination of both cash (in the form of euro) and 24KT currency grade gold (in the form of Karatbars)
