I think retailers should price things on the counter with the tax included in the price.
There are cities in CA that have a 12% Sales Tax--normal state sales tax is 6%. They also have special lumber tax and disposal fees, hospitality fees, etc., that are added when you get to the counter.
But, when blacks complain about sales tax at a mom and pop, they are trying to get a discount.
It is other countries that are deceitful. They hide the fact that some of the money goes straight to the government, instead of going to the shopkeeper to pay for manufacturing and distribution.
