I think most people would rather just live in ignorance than accept the reality and undertake the harsh task of trying to set things right. Countries like America and Australia didn't just come about from a lucky accident of history, some boat being blown off course and landing in some magical new land or whatever, they were built from centuries of genocide, slavery, and exploitation, and by us continuing to participate in these societies and enjoying the comfort and material wealth that comes with it, we in some sense share some culpability for the oppression and suffering, past present and future, that's necessary to make it all function. But at the same time, it's not possible for us to just stop participating in society, just the act of existing in this world, posting on these forums with electronic devices that were built with sweatshop labor, or doing a daily commute using cheap gas made possible by the bombing of countless Middle Eastern towns, all contributes to the continuing misery of the rest of the world. So either we have to radically change everything about our lives and accept a significantly diminished quality of life, or we can just tell ourselves that all these bad things are good actually and that actually we did everyone a favor by building this modern country on top of land that a bunch of savage tribes were letting go to waste, and that all this cheap labor overseas we rely on for all our stuff is actually creating jobs and developing their economies, and that bombing Iraq was necessary to spread freedom and democracy or whatever, and that you know, even if America does do some bad stuff it doesn't really matter cause you know the world is full of bad people like the Russians and the Chinese and Islamic terrorists and that if any of THOSE people were in charge you know things would be MUCH worse even.
