Then you'll have the Democrats and special interest groups demanding that their pet product or service be exempt from the Federal Sales Tax (My proposal).
Which means that the tax will be higher. Everything should be taxed at the same rate, then the rate would be lower.
Exactly. Any exemptions from a NRST is just a way to let the nanny state dictate what is "good" and "bad" for us. No exemptions and a universal rebate is the way to go.
