Personally I have no idea what the typical atmosphere is on university campuses. Of course I'm aware of the protests that make the main stream media, but it seems silly to just assume that those small numbers of protests are broadly representative.
Moreover, old people are unlikely to support revolutionary changes because revolution always causes some sort of turmoil, and you can likely only begin to reap the benefits of the new order after a long time, e.g. 10-15 years. You're less likely to support such a change if you're going to be dead by the point when its benefits start becoming apparent, or when a significant amount of your remaining time will be spent in the turmoil before that.
