Why are white people angry that Arabs and Africans are invading Europe?

Consider a few things here, look at all the wars in the middle east that have been cause because of white nations. Now those places are practically unlivable because of constant war and new factions always arising because those countries have no military left.

Now look at Africa, a continent that has a ton of valuable resources, yet it has been colonized and exploited to the point where all the black nations are so poor, now they want to seek a better life.

This is the white man's doing, you can't remain on top of the world forever. Soon China and India will be 1 and 2 and all the white nations will not be powerful.
