Canada's per capita income is higher today than it was 60 years ago. Back then the British and French robbed resources from Asia and Africa, paid workers there almost zero, and repatriated profits back to the home country.

In fact, without robbing Asia and Africa, there would be no Industrial revolution. British firms needed markets, and they forced their colonies to buy their manufactured products, especially textiles. And opium. The profits from these enterprises funded the Industrial Revolution.
