People on Zig Forums like to try and pinpoint different times in the history of the West where things started taking a turn for the worse for Europe.
Our present problems really have their roots in what took place starting in the 15th century.
The Bible taught man only of the existence of three continents: Europe, Africa and Asia. As Europe became aware that America was not, as they had thought, part of Asia, but indeed a distinct new continent, a domino-effect was set off leading people to question ecclesial and royal (the two were closely linked) power.
The Enlightenment was propably one of the worst things that could have happened to Europe. It gave rise to dangerous Jewish ideas such as humanitarianism, equality, cosmopolitanism. The USA itself was founded upon these "ideals" and adheres them to this day. Communism and Socialism also derived from these "ideals". In essence, they provide a plebs' outlook on social-political topics.
As commies started tearing down one colonial governance after another, especially in Africa, the national power of Colonialism gradually began to shift toward a corporate approach in the mid-to late 20th century. International businesses expand their activities to every third-world shithole they can squeeze a few resources or cheap labour out of.
Meanwhile, Western nations struggle with unemployment and are left behind in terms of jobs.
The only people that truly benefit from this arrangement are the Jews.
No significant place on Earth has managed to keep their own culture alive and intact over the last millennium as every single third-world shithole you see in pic related has been westernised to oblivion. Sure, they might have some of their temples or traditional food, song and clothing left, but still their people all watch TV, they drive cars, they wear suits, and they use cellphones.
Do you really think it was God's or Kek's or whatever deity you worships' plan for there to be fucking skyscrapers in Botswana? Do you think there were meant to be universities in Nepal?
All non-European peoples have basically absorbed European culture in one way or another, and now they think they have a right to "reap the benefits" of their cultural imprint by coming to our land. Which brings us to:
The current waves of migrants that came to Europe would never have been possible without Colonialism taking place. Every brown person in the world has been westernised to some degree, and now us White people get to keep carrying the burden of removing that last bit of savagery in their subhuman hearts. Our "humanitarian" outlook caused us to tear down the walls around Europe, and letting the people we once controlled in their lands via colonial governance to flood into our countries and demand their "rights" (aka gibs).
TL;DR If you do colonialism, you need to genocide as well
