I will die of old age before a 白 party appears, if I cooperate with the 黒 parties. And the 白 and the 黒 hate each other; the 黒 will never willingly let the 白 take power. It doesn't matter how nice the 黒 parties are; they HATE the 白 parties for ideological reasons. There's no way around this - they truly are an existential threat to the other.
Therefore, the only real way to get a 白 party to take power is to overthrow the 黒 parties and install a 白 party. Or, wait until the 黒 parties are sufficiently weakened from infighting and civil war to allow a 白 party to take over. I see no scenario where the 白 can peacefully take power in a 黒-dominated country. Or vice versa.
And the education issue is precisely why it is imperative the 白 take power. Their political system desires to give people a proper education for the purpose of societal stability. The 黒 are far too fickle with education.
I shall answer, because I am a firm believer in capital punishment.
Death should be given because death should be the punishment for all crime. The white blood cells inside your body agree with me - they are eager to give the death penalty to any criminals infesting your body. There's no pardons or rehabilitation or anything like that; your white blood cells know that there can be no tolerance for crime.
