My profit model is far conservative. As you can see in the link, Nike’s annual profits before taxes exceeded 13%.
Furthermore, your statistics citing “90% of corporations paying no taxes” are wildly out of context as millions of corporations are in fact individuals or very small concerns.
Most businesses fail, so I would expect to see that most pay no tax. Try narrowing your sample base to viable businesses before shooting off irrelevant statistics.
So what? Whoever they are, they have less money with which to reduce prices.
"Try narrowing your sample base to viable businesses"
Right. As soon as you explain how you went from your inflated 11% in embedded taxes to 20% when you add "miscellaneous".
