You mean they ruled in favor of the states wanting to collect sales tax.
While I agree with you about leveling the playing field, it's also not fair to the businesses. For instances, business in state A has nothing to do with state B, yet state B decides that they can tax business A. This would be like state A, charging tax to Italy when you buy something from Italy. Yeah, lets see how that flies.
On the flp side, it's still not fair to brick and mortar stores because they are paying for real estate that internet sites do not pay. It's like MP3s and digital streaming content etc. You either adapt of your business dies. Sales tax isn't going to save brick and mortar stores. This only helps the states who already shot themselves in the foot because of corruption of state and local finances.
I live in Connecticut and the super rich in Connecticut are a major issue why Connecticut has such budget issues. The richest county in Connecticut is Fairfield and that is where Greenwich, CT is. The most massive and expensive houses in Connecticut are in Greenwich and Darien, both in Fairfield county. (a HUGE portion of the super rich bankers in the Financial district live there) Anyhow, Fairfield county has the second lowest mill rate on property tax. So the highest priced homes have the lowest tax rate. Corruption at its finest.
