Think through the effects a little bit if you do this you'll get big corporations buying their entire supply chain to end up at 1% tax to pay. The more complicated the supply chain the more expensive the products would become.

e.g say for a car you'd have 10 companies chained (mining company, refining company, plastic creation company, ...)

You'd end up with ~10% tax on a car but 2% for milk. Makes it very tricky to do specialized high tech produts
