Every thing is relative. I too am paying taxes when I buy goods and services. The difference is, on a quarterly basis, I send a check to the IRS. They don't. Do you, for G-d's sake see the difference?
Of course I do. But where did that money come from? Your customer! YOU aren't paying that money.
Look, what if you didn't have to send a check to the IRS? Wouldn't you charge less for your product or service? Meaning, of course, that your customer, not you, was paying that tax.
All you're doing is forwarding their money to the IRS every quarter. It's the price of being a legitimate business.
Oh, keep in mind that under the Fair tax, the criminals and illegals won't be collecting the tax on their products and services. So they'll end up cheating that tax system, too. Do you, for G-d' sake see that?
