Note that I was NOT justifying the cost difference, but just noting where SOME of the cost differences may occur. I agree that in some cases it's anything but free market trade. In some countries you do not have to pay directly for health care for instance, and I would expect that some of the taxes you pay are used for such social benefits that you all enjoy that we don't here in the states.
US stockists are barred from sending instruments/equipment overseas by such companys as Mesa, Fender and probably many more, my friend recently purchased a Fender Strat in the US for nearly half the price that they are in the UK.
You actualy pay for health care in the UK by 'National Insurance' contributions out of your wages this also takes care of your state pension, next year when I'm 65 I'll get the princely sum of $200 USD per week for 50 years contributions including a stint in the army.
