Democracy is essentially mob rule. It's great when the mob is doing what you want, not so great when it isn't.

Currently most Western democracies are designed to protect minority rights against the majority because of this. In fact, the Bill or Rights in the US can be seen as a great example of this: it prevents the current majority from removing rights deemed essential.

If you look at states that have weak individual property rights (all the communist states, most of the Iberian colonies) you can see the issue: weak property rights by individuals go hand in hand with authoritarianism.

Those who want "change" always want to destroy the system. Historically speaking, that has led to disasters of one sort of another.
