If the market answers all societal problems and questions, it is not difficult to see how a rational (though perhaps somewhat unreflective) individual can come to view the market as providing answers to all personal situations and problems. And so what does the market teach? "Don't do anything for anyone unless you get something in return" or "There is no common good or community...only individual good."
Even traditional conservatives see (or are beginning to see) how the marketization of human and societal relations is destructive.
