"Do you have any idea what a nightmare it would be for a small online retailer if they had to figure out what sales tax to charge on every transaction in every locality in the country."
As an online AND brick and mortar retailer, I can imagine. It would be DIFFICULT! I mean, you'd have to have some sort of computer program that accessed a table, geez, maybe HUNDREDS of records large, and then report to the business owners where to pay the tax to! I mean, it would take a good, 5-10 minutes for somebody to program, and it would have to be updated every few months. Whoa! Talk about an inconvenience.
That's a LOT more difficult than trying to run a brick-and-mortar store that pays significant amounts of taxes and having to compete against businesses that don't have to collect sales tax from their customers.
Please not this entire post was tongue in cheek. Except for this line. Oh, and the quote I was responding too... that was literal.
