Look at it like this: motors are a recent invention. It used to be if some group was big enough to have a city, they had slaves or slave-like laborers that were looked down on and generally abused. Everywhere. Including European serfs. Even Vikings made slaves out of Englishmen. Everything from reaping wheat to making nails was the result of physical labor so an underclass was necessary once you were bigger than a village/town.
For a bunch of reasons, Europeans developed better ships sooner and so had the opportunity to exploit the labor of other peoples as well as their own countrymen. That set up a cascade of development. The French revolution happened early enough that it served as a warning to other governments to spend some resources pacifying the masses at home. The masses were never in a position to know what was going on beyond their own borders, so the people in control – the people gaining all the rewards – had a psychological reason to mentally frame the people of their conquered colonies as inferiors. To be fair, almost every country has considered themself to be a better people than all others. Everyone thinks they do things the best way.
I feel pretty sure that if the Chinese of Japanese had come to Europe in, say, 1200 A.D. with ships and guns, Europe would have been colonized. The same goes for any other power. Sigh I sometimes wish Carthage had defeated Rome.
