Yeah, and who does the pimp buy his pimp-mobile from? The car dealership, so therefore there are taxes "hidden" in the cost, since you so eloquently stated that
"Now, Achimp, in America, we already pay a sales tax on items, along with state taxes and possibly city taxes."
Your use of bread as an example is flawed. Under any normal standard sales tax system, items deemed to be essential are NOT taxed. That includes food; how lucky for you.
In addition to that, your view of standard sales tax is flawed! A sales tax applies to EVERY KIND OF SALES TRANSACTION, not just what is deemed to be the end-consumer. So you eliminate the tax that is placed on grain, but add a sales tax to that transaction instead.
Let's look at your little example, and assume that "KA-CHING" means that sales tax has been applied:
Farmer sells to grain warehouse. KA-CHING. Grain warehouse sells to dough-maker. KA-CHING. Dough-maker sells to bakery. KA-CHING. Bakery sells to store. KA-CHING. You buy the bread from the store. KA-CHING.
You are merely replacing a bunch of taxes with one tax, and it all adds up to the same amount in the end. (i.e. replace all the KA-CHINGs with "grain tax" and "dough tax", etc.) Since you are so pro-capitalism, you can't begrudge a merchant and honest profit, so the price goes up at each level. Are you being taxed any less in the end? No.
All you have succeeded in doing is removing the income tax that you whine so much about. But wait! We'll have more money so we can buy more stuff! No, you won't. Take some marketing and consumer behaviour courses, Vince. People don't typically buy stuff just because they can; they buy stuff that they think they need. You don't see me with a dozen TVs just because I can afford them.
You are using all the same arguments that the Conservative government used in the late 80's when they were introducing the GST, our national sales tax.
Prices will go lower! Everyone will have more! No they didn't. No we don't.
