Are you pushing, riding, or blocking the Winnebago?

Today I came across this article from Inventors Digest featuring podcast star Adam Carolla.  It captions his life as a metaphor for invention – the ability to try, fail, and improve.  And it makes a good point that America, and each of us living in it, are all constant inventions.  Some fail, some succeed, most are trying to improve.  Carolla proposes his own metaphor for the country-countrymen symbiosis: some of us are pushing it along, some are freeriding inside, and some are out front getting in the way.  Which are you?
