And since you say my income taxes on my business aren't a factor of producton, then golly the income taxes that I pay are not a cost somehow.
Well Alice, I hate to tell you that your book does't model the real world.
I do pay my income taxes from my sales revenues and I do make my price higher due to the obvious and trivial fact that they are one of my costs.
Book formulas are intended to model and explain the real world. But when the real world is obviously different, it is easy to conclude that the model needs to be fixed.
Why are you so invested in a book model that is obviously not working?
You do not grasp the point of the argument and your belligerence toward actually studying the subject will prevent you from grasping it. Business revenues and Personal income from business profits are different things whether you stick your fingers in your ears and yell "it ain't true" continously.
My understanding of the "model" allows me to see through the inchoate quality of the FT. And it allows me to correctly interprete economic and financial events.
