That's because in Europe 1/3 of the cost is taxes! They are taxed big time on fuel in all these countries you are talking about.
Our government gets their money by other ways through taxes.
For example; Luxury Tax, Recreational Tax and one of my favorites Gas Guzzler Tax!
The last time in this country crap like this took place we had a party didn't we!

Were the hell does Eddy come off with spoiled most of us here earned what we have it wasn't given to us!
How come the gas varies so much from state to state?
Here's what gets me. I've seen signs on pumps in the past letting you know that 43 cents or whatever the number was what you were paying in taxes per gallon! It's the reason taxes were figured into gas already instead of having sales tax added at the register like they do everything else. In other words, they were putting it to us that badly.
Now I've heard that some states are b*tching because they're getting such a low percentage of tax since the price of gas has gone up so much. That's how the b*stards think! It's not about what they NEED. It's about whether they're getting from us what they somehow think they're ENTITLED to! How about instead, they give us some rebates for all the outrageously high screwings they already gave us for years when gas WAS only a buck or so a gallon! When half of everything we make goes to the government, how can we even HAVE a national debt? That's insane!
One example. New Jersey collects fuel tax on every gallon it sells like every other state, along with collecting tolls on the turnpike (Which I'm sure has only paid for itself thousands of times over), not to mention that you have to pay to get out of the state on almost any bridge you cross to do so. Now they want to turn I-78 and I-80 into toll roads. They want to add tolls to roads that are already paid for! WTF are they doing with the taxes they ALREADY COLLECT???
It's the same state that wanted to put a meter on my girlfriend's parents' well to charge them taxes on the water they pump out of their own ground (because, I guess, making them pay over $2,000 in property tax EVERY QUARTER to live in their own house isn't enough) because, as they tried to reason, that's not their water. It flows through their property from somewhere else! I was there the other day and her mom put some potted plants outside to catch some rain water that was falling. I was thinking "Boy, don't let the government catch you doing that because, that's water that's falling on your property from somewhere else!
If they could put meters on our mouths and charge us for the amount of air we breathe every day (Cuz, that's air that comes from somewhere else, obviously NOT ours!), they would have done it already!
The only reason all our taxes are spread out the way they are is, IMO, that there WOULD be a revolt in this country if you just took half off the top as soon as people make it.
