Saudi Arabia is a puritanical state that claims a monopoly of wisdom and virtue.

No party has a monopoly on wisdom. No democracy works without compromise. But when Governor Romney and his allies in Congress tell us we can somehow lower our deficit by spending trillions more on new tax breaks for the wealthy - well you do the math.

If you allow for a purely capitalistic society without any type of regulation at all you will get one monopoly that will eat all of the smaller fish and own everything and then you'll have zero capitalism zero competition - it would just be one giant company.

Our public school system is our country's biggest and most inefficient monopoly yet it keeps demanding more and more money.
