You clearly don't know what you're talking about. Chinese workers comprised a small portion of the workforce that built the Canadian railroads, only participating in the BC stretch of the railroad and usually only employed in the most dangerous stretches of construction. The rest of the workforce were "navvies", European workers, who built the rest of the lines up to BC and who otherwise would have built the railroad in lieu of Chinese workers. While contributing, it wasn't the Chinese who built our country, it was the people like John A. MacDonald who had the vision of a Canadian confederation... workers would literally have come from anywhere. However, the Chinese were a convenient BC workforce given that they seemed to have no self respect, working for much less than the rest of the workforce and had no concern about personal safety. That seems apparent or they just wouldn't have come in the first place. It is reprehensible how they were treated, nonetheless.
