Professional guilds - legal bars, medical boards, engineering, academia - you're pretty much excluded from all those fields lacking a formal degree accepted by the mentioned institutions, even tough you can have the required skills and even experience (as a skilled immigrant for eg., you can even have a degree from a non-accredited/foreign education institution). The monopolistic nature of this system is nicely illustrated by the "diploma mills" that allow people to get hired for the job requiring a diploma without completing the education program, perform their jobs successfully for considerable amount of time and then when/if discovered "cheating" get fired - without actually failing to do their job at any point, just because they don't have the degree. Granted this is logical from the employers point of view as the legal liability is huge but that's the result of the system.
>I think it's ironic that the OP used a computer and the internet to publish his propagandist rant; an action that would've been impossible without all the academic research into computing and networking systems in the last few decades. I'd argue that the economic fallout of that research alone has more than paid back whatever money the US government has invested in universities.
I'd argue that you don't consider the opportunity cost and the crowding out of R&D investment in that assertion and implied that without public funding the academic work wouldn't be done. Here's a different view of that argument : http://www.youtube.com/watch?v=C_PVI6V6o-4 , also he has a book on topic.
