Wow, I know you might not take it for much coming from me, but great post. You've put it clearer than I have been able to (and I've been trying).
Thanks. Most people want the cliff-notes version of what happens to taxes paid at the entity level. VERY FEW PEOPLE have the inclination to fully understand the "shifting sands" of incidence. And what is true today with respect to the ultimate incidence of a tax is NOT NECESSARILY true tomorrow.
Analogizing to shifting sands is therefore appropriate and helpful to most.
The ball to watch here is the TOTAL purchasing power of individuals and their ability to obtain the same basket of goods that they are able to obtain today.
