They could end their debt crisis in a few years if they raised fuel taxes. They pay about 12% compared with nearly 70% here in the UK.:
Well that's an interesting claim as it can be checked quite simply.
Raising tax on gasoline in the US to UK levels would raise an additional US$500 billion per year in federal tax.
Current federal dept is US$16 trillion. At a 0% interest rate it would take 32 years to pay off - unfortunately the interest rate isn't going to be 0% over the next 32 years. Let's say it's 5% per annum over the length of the loan.
5% of 16 trillion in year one is, er, 800 billion per year. So as you can see, your extra $500 billion doesn't even cover the interest payments, so it can hardly end their debt crisis at all, never mind in a "few years".
Though it would be $500 billion extra income a year so would definitely slow the increase.
And that's assuming that gasoline consumption habits don't change because of the tax increase and they keep raising that cash, which of course is a false assumption.
No, unfortunately the US is stuffed, they can kick the can down the road but eventually they are going to meltdown. As they have significant natural resources they will come back a lot stronger than we will, if we come back at all.
