Re: $20 a gallon gas proposed.....
The price of a gallon of gas is the same world wide.
What you pay in your individual countries is governed by the countries added taxes.
Denmark has a whole lot more social services that the US. and you pay for it.
Where I live in Canada gas is $4.12 for 4 ltr./3.8 US gal. We have a first rate public transit system and since I'm retired, the 2 knees I just had replaced didn't cost me a dime. We just pay as we go.
