I grew up on three continents:) and seen poverty, civil war and discrimination up close as a kid. All the more reason to want to understand the mechanisms and participate in honest dialogues to sharpen my understanding of how societies (dis)function.
And yes, I agree that general ignorance is widespread and that few understand the level of manipulation their governments and corporations wield in the global arena. It's why I donate to Scheer.com and follow news on multiple channels, also non-Western ones as I know the high levels of censorship in our mainstream Media.
That means I can also put your sentence "how much damage have genocide, culturocide, theft and exploitation by the west caused to humanity" into a wider historical perspective.
The Roman Empire, which lasted almost more than 1000 years, did exactly that to all the civilizations they conquered. Most of which were in Europe. Slavery was their speciality and the fuel of their economy. It only ended when the Germanic tribes put their mutual animosity aside and, at last, united to fight off the Romans.
This cooperation changed their future. And no they didn't start their new history page "privileged" but with devastated and pillaged societies. The same for the Polish against the Russians, the Dutch against the Spanish, etc.
In fact, the most "privileged" namely Spain, Portugal and Italy are today amongst Europe's weakest nations.
So, you might want to use some maths to measure the hard correlation on the societal level between "cooperation-to-succes-rate" versus "privilege-to-succes-rate". It's why non-colonial countries like Finland, Sweden and Norway are leading the charts.
The "privileged" argument is a typical post-modernist tool for claiming the rhetorical position of victimhood in today's political arena. It's only about power not about achieving genuine human progress. The philosopher Tinneke Beeckman explains this political mechanism quite well in her book 'Power and Powerlessness'.
