The highest rate is 1.5%. Retailers come in at .5%. Again, that's for normal businesses; the highest rates are actually paid by nuclear waste disposal companies.
And yes, one individual business might well swear at the tax -- they can see their overall profits at 3.5% (and as you say, mall retailers in that one survey at 0%), and the individual owner thinks that if only the tax were lower, they would make money. That wouldn't actually change the economics of the situation. If they charge less, the lack of profit means that the business isn't worth it. If they charge more, they lose customers to cheaper stores. If everyone had smaller expenses, everyone would charge a hair less, and the overall profits would be unchanged.
Stated more broadly: if a set of stores can't make money with the .5% tax, they won't make money with a .4% tax, either. Or a .3% tax.
(And BTW: my immediate assumption when I see the phrase 'so I decided to get the fact' is 'that person is a troll'. You're not helping your case by citing as your source an 'ask the expert' column that quote data from shoe stores from 1999. Luckily the facts that they do cite match my pre-existing knowledge, so I'm not kicking about it. But it's not a very definitive set of data.)
