But with online purchases, the state does nothing - this is just a naked grab for more of our money.
For the state the purchaser resides in, it still provides services in the state where the business resides, but it doesn't get the benefit, unless it gets the sales taxes from the business....but how is that business going to get those taxes from the purchaser, as would be the case in a brick-and-mortar purchase.
However, the other side of the coin is that since having out-of-state consumers is an advantage to online businesses that the brick-and-mortar businesses don't have...the online business should be happy to pay the sales taxes without having to get them from the out-of-state purchasers, it's just a cost of doing business around the country/globe.
They get healthcare, of course. hehe
(end sarcasm) I agree. Your observation is excellent.
