I find the opposite, that the most adult and mature folks I know are interested in fulfilling their social responsibility.
They may not be interested in the straw-man version you've proposed, but your definition is not the end-all, be-all of what "social responsibility" is.
We need a clear definition of "social responsibility", as many use the term to mean "collective responsibility", which really means 'foisting the costs on the politically powerless".
I see "social responsibility" as personal, which means that you are personally responsible for the society you live in; this is difficult when the government crowds out charities, and gives many people reason to free-ride.
Thus most people with any life-experience want nothing to do with it.
