In literal terms, I suppose so. Rather, I recognise it as an inevitability.
It's only viewed as inevitable because of mindsets like yours that refuse to see the bigger picture of things.
The third world was trash long before Europeans arrived from the 1600s onwards, and has been long after our fathers left. Over 50% of the population of Africa (yes, the continent) live on less than 1USD a day. Considering that trillions and trillions of dollars has gone into support for these sh*thole countries, yes, it is their own greed and inability to succeed as nations and a civilisation that holds them back.
No, the rest of the world got on just fine without colonialism. It was colonialism that destroyed those people's cultures and raped their psyches. You try to go centuries of living under systemic racism, being told you're lesser and not even a human being. You go centuries being enslaved and brutalized, forced to give up your native names, your native religion and have some invaders steal your resources, keep you in poverty and deny you an education.
You really don't understand history and its consequences at all. Nor do you understand that just throwing money at charities and having parasitic organizations like the IMF and World Bank get involved is a recipe for disaster. That money doesn't go to the people at all. Charity is a scam.
Tell me, why, when black and brown people attempt to establish self-determination and throw off the shackles of colonial oppression, their leaders are slaughtered and overthrown and puppets put in their place who will follow the script? Ever heard of Thomas Sankara? Salvador Allende? Muammar Gaddafi? Hugo Chavez? Steve Biko? Malcolm X? Che Guevera? Do you know what happened to them? All of them attempted to raise their people up, strive for self-determination, had widespread support among the common peoples and all of them were murdered in coups or assassinated by Western powers who wanted to keep those people enslaved so that they can steal their resources.
There is no reason at all why Africa is suffering so much. It's vastly rich in resources. Africa should be the richest continent on the planet. But it's resources are being stolen by corporations and their lackeys in governments. These dictators and warlords are funded by Western interests. Where do you think they're getting those weapons from? Go read about blood diamonds, for one. You can also read about the global drug trade and how Western governments have their dirty hands in it. How do you think all these hard drugs got into the ghetto? Gary Webb exposed the CIA links to the crack epidemic in the LA ghettos and he ended up dead. They say it was a "suicide", which is a crock of **** if there ever was one. The whores in the mainstream media all shouted him down and tried to destroy his career. This is the real world. This is the world of lies and deception.
The concept of "race" and white supremacy is a fiction that was made up to rationalize the conquering, destruction and enslavement of peoples around the globe and to help the masses "back home" feel better about what their disgusting rulers are doing (nevermind that most people in the West have never benefited from the global rape of the peoples of the world since most of the wealth goes to the already-rich).
You need to educate yourself on how the world really operates. We are all human beings and there is no proof of any inherent biological inequalities that separate groups. It's a nonsense and has been disproven by science. I am not lesser than you because my dad happened to be black. Phenotypes are random and don't matter.
