As for Europe, I'm sure people were still enjoying meals and a nice round of drinks on the Titanic after it hit the iceberg. That doesn't deny it sank though nor that it would. Demographic changes, currency issues, etc show Europe is failing.
Your experience continues to have a racist tinge to it whereby you hold up your European examples and the best and note the places in the world Europe exploited and damaged as the examples of what is wrong. Let's have Nigeria cart off goods from Germany for 150 years and afterwards when Germany can't seem to get it's shit together, we can hold it up as an example what is bad.
I'm referring to the effectiveness and reach of government.
Nigerian society is not damaged because Nigerians are black.
That's a connection made in your own mind Nick, and I can only speculate what that says about you.
EDIT: I was a bit mean.
