Let me just echo the fact that when The College Kids Today attempt to exercise the one bit of power they potentially have - influencing the actions of college administrators - they're generally mocked and derided. Divestment campaigns and improved sourcing policies might not save the world - they might not even be particularly helpful! - but they're the one way students can actually draw attention an issue and have a clearly defined and potentially achievable goal.
It's always tempting to say The Left and The Kids are doing it wrong. So start your own damn revolution.
