Seriously, is survival in cities even POSSIBLE?

I have a very dim view of it. IMHO, cities as we have them now are obsolete. They don't really serve any purpose except as concentrations of government power. They are magnets for government dependency and serve a function to overwhelm the productive countryside in elections with voters who have an urgent need to vote for those who keep spreading the "free" cheese and Obamaphones.

They no longer serve any purpose in the free enterprise economy. They are centers of tyranny.
