Youth and Libertarians

Pratt's recent post regarding the potential demise of libertarians as we older folks pass on suggests there may be a relationship between the importance of liberty to one and one's age. "Freedom is nothing left to lose" the song goes. Is that true? Those supporting status quo surely don't want the freedom of libertariansim. It should be those on the lowest rung of the totem pole that most support freedom. So have government programs destroyed this -- are the youth losing any interest in freedom as they believe in larger and larger entitlements? Some research on this topic might be of interest; all I have is anectdotal evidence that there are few young or old who understand what liberty is.
