They will never admit their wrongdoings.
No government ever admits that they did something wrong. Instead, they double down on proving they were right by saying that the people they hurt deserved what they got. They were bad people anyway. They come up with twisted ideas to justify their behaviour.
Socialist governments don't stop when things go south. They become more socialistic.
Racist/classist governments don't stop either. They come up with propaganda to vilify the oppressed class.
Their goal is to ensure that the oppressed are viewed as so wretched and inhumane that the majority becomes indifferent towards them. Once the majority views the oppressed class as so inhumane that basic morality does not even apply to them, all hell breaks loose. The government can then tyrannize the oppressed as the majority cheers for it. In fact, the majority would likely assist the government in its evil deeds.
We must elect young leaders.
Reconciliation happens once old people in power retire or die off. Since the new people have not done anything wrong, they don't have to come up with twisted ideas to justify what their predecessors did. People don't become evil naturally. They become evil because they once did evil things and now can't accept their wrongdoings.
If a people want to change the temperament of their government, they must elect people who are much younger -- almost one or two generations younger -- since they are less likely to have agreed to/followed/participated in what happened before them. These new people would happily reverse the damage that was done.
We see this in almost every post racist/classist/socialist nation. New leaders don't aggrandize their predecessors. Instead, they call them out and talk about reconciliation/restoration. I do understand, however, that this isn't quite possible. Most constitutions do not allow people under 35 to run for public offices. There is some sort of a universal misbelief that leadership has anything to do with age. Half of the world calls Jesus king, but they would have not allowed him to run for president. Ironic? I guess people under 35 can only be kings.
