There are still a lot of necessities that are taxed, like adult clothing, hygiene supplies, etc., and a lot of non-necessities that are exempted. Last I checked, a baggie of corner store candy is not exempt but a $5k wedding cake would be. A wardrobe of designer children's clothing is exempt, but work boots for an adult are not. So they have tried to make it less regressive, but that's hard to do with a sales tax.
