Hi tkc,
Well, yes, you have to be sensitive to volumes and to price on the assumption that some items will perish. There are variables. Yes.
But as businesses go, it doesn't look like a relatively hard one to run, especially as a franchise operation. Manufacturing a pizza is not the same thing as baking an iPhone. There's not much need for innovation. etc. I am not contemptuous. Just not in awe, at least not as apparently I am meant to be.
Jobs is somewhere else on the spectrum than Cain. Neither is Einstein.
And to suggest that running a pizza parlour qualifies a person to run a country - which is the claim coming from the right - is ridiculous. It is treated as an object of reverence that a person runs a business. I think that is a mythology which it is high time to challenge. Plenty of people are capable of running a business. Even plod. I suspect running a country is harder.
