Arriving at common sense

My town,  Fresno, offers cheap living.  $300 a  month and mutual common sense gets anyone a room with a light and bathroom/kitchen privileges.  Mutual common sense is three people who understand the basic economics of electric bills, rental agreements, and how to live three adults in a house.

Thus the problem, there is no way to cheaply replace common sense, especially in metropolitan life. In Fresno, we board up empty houses while people are homeless.  These homeless could get $300, but they fail in mutual common sense.  The public sector would bring their pension burdens and inefficiency, and replace common sense with bureaucracy.  Try doing nothing, and when the subject comes up say, sure, let's find three with common sense.
