Other things are much more important. In a sense all Americans are businessmen. There are few countries that value business, entrepreneurship, business people and property as highly as Americans.
As for America valuing businessmen/entrepreneurs/property more than other countries, how do you get to this conclusion? Have you worked with people from abroad before? From Western Europe to India, China or Africa I have seen businessmen/entrepreneurs/property being held in very high esteem. I'm not sure how I would index how society values them but I would be hesitant to say the US values theirs more than other countries.
How many old people are stuck in a job because of health insurance. There's a lot of old people.
