Author here. I very much appreciate your polite tone! I'm aware that taxes on items for resale aren't treated like in the toy model. (This is mentioned in the article already.) Can you please take a look at this article and let me know if it changes your view: https://www.cost.org/globalassets/cost/state-tax-resources-p...
Thanks for the interesting link. I've read it and here are my thoughts: - The paper talks about business inputs, which is anything a business purchases. Businesses need to pay sales tax on items, unless they are intended for resale. So they're going to be charged sales tax for the coffee machine for the break room for example. - I disagree that sales tax is a "household consumer"-only tax. It's just a consumption tax…
FWIW, many/most states exempt services, so sales taxes are generally much more limited than a true consumption tax.
