Since when are "vertical integration" and joint production of goods 
assumptions made in a typical intermediate textbook when deriving labour
demand?  If you really *wanted* to be honest, you would explicitly outline how
your assumptions differ from those made (explicitly or implicitly) in
"mainstream textbook treatments" and discuss why these assumptions lead to
apparently contradictory conclusions.  My guess is that you aren't capable...
