well i wasn't asserting a fact... i wrote, "a lot of what rand wrote rings both true and effective" ... the term 'rings true' means "seem genuine" and implies opinion
my reply to the rest might be off the wall, because i'm not sure exactly what you're saying...
Jimmy you stated the following:
"when a person, group, city, state, country works in their/its own best interest, the best interest of the majority is served"
I presented a series of counter examples that share a common unifying theme: In each of these example, a rational self-interested individual acting in his own best interest will not serve the interest of the majority.
Pollution is probably the easiest case to consider. Suppose I won a factory that produces widgets. Each time I produce a widget, I release pollution into the air that makes people sick. Furthermore, I - the owner of the plant - don't bear the entire cost of the pollution. As the owner of the plant, I chose what quantity of widgets to produce with the goal of maximizing my profits.
I claim that the presence of the externality (pollution) means that the profit maximizing solution for the individual involves producing more widgets (and more pollution) than the profit maximizing solution for society as a whole.
I'd be happy to provide a detailed mathematical example for any or all of the cases that I specified in the my original posting. I'm also happy to relate these theoretical examples back to the "real" world. it should be quite easy to see the linkage between the pollution example and many of the real world debates going on right now.
