There is a quality called "contentment". Ask yourself a question? If Europe was poor/ignorant/weak and East can exploit them, then they could have been used as slaves, right? After all, that was easy. Isn't it? Why that did not happened? Because there was no interest/intention in the so called "world domination" or "we are better than you" ...etc attitude.
This is the mindset/weakness of some part of west where you get confidence of your power only if you colonize/destroy other country. But if you are self-aware of your powers, then you do not need to exhibit them unless they are needed.
Concept of Colonization/exploitation intentionally was not part of Eastern mindset/attitude. If you want to speculate, you can but that cannot be truth.
