First, how do you discount academia? Especially those who were professors and teachers and not just plunked into university president/dean positions. Take Sec of Transportation Ray LaHood (Repub from IL). He was a grocery bagger then a high school teacher.
Second, (more importantly IMHO) why do I want MY government run like a business? A US owned business's top priority is NOT to create jobs. Its to maximize shareholder wealth...I'll pass on having a bunch of business men calling the shots on what the USG should be doing...oh wait, they already do. Guess it doesn't matter....I watch Fox (Brett Baier...still a fan of Brit Hume when he occasionally is on) but Glenn Beck is just like a Keith Oberlman...just opposite end of the garbage dump.
