White people built the west?  You think they did it ALL by themselves?  I assume your aim is not to appear ignorant/bigoted, parroter of white supremacist, republican steve king playbook/narrative.   

What would the U.S. be without slave labour?  What would Canada be without 'one dead Chinese for every mile of railway track' built to connect the country coast to the other?  Where do you think the idea of written laws -code of Hammurabi came from (and that is now Iraq;) current-day numeric system -India; idea for surgeries, plastic, dentistry, cataract - (Egypt, and what is now India, Pakistan); and lets not forget elevators, microphones, pacemakers, blood transfusions, and of course IPads, iphones. I could go on but you get the picture I'm sure.

We are interdependent, we stand on the shoulders of giants; give people due, we'd be a better society for it.
