The design incorporates the idea that we're going to behave with some sense of compassion and justice. There are, famously, four boxes of liberty[1], and if the majority uses the first three to the detriment of the minority, we'll find ourselves the target of the fourth.

So out of simple self interest it behooves us not to just say "the status quo should be hard to change". When we see an injustice, we should fight to change it, even when it's not to our own immediate advantage.
