I find it rather revealing (actually not) that you would use Joe the Plumber for your example. It still stings you liberals that Obama revealed his real intentions to Joe, huh?
As for the VAT. I just had my first real experience with it yesterday. I had already booked my flight and my lodging for a trip to Charleston SC. for later this month when I figured I better rent a vehicle too. I was about to click on the pay button when I seen a huge jump in the cost. After I caught my breath, my significant other pointed out to me that I was on a European web site. OMG People, we do not want a VAT in America. I personally think it will be a deterrent from spending hard earned money and therefore stall any resemblance to a economic recovery.
