The trickle down theory works when people are more self interested than neurotic. Trouble is, there are a lot of neurotics out there.
Look at Hollywood’s obsession with tearing down heroes. They hate the idea that heroes are heroes because they are better. Again, with the “winner at life’s lottery” idea.
There is so much negativity and downright evil in such bitter jealousy and envy. But it is why the Democrat party is the way it is.
At some point doesn't self-interest interfere with a healthy market place?
I suppose a person has a self-interest to make sure that his market is strong and his customers are content. I'm off to work, but "self-interested" in your response. :-)
