What are the positive effects of imperialism?

A positive effect is seen in document one called "Modern
Progressive Nations," it shows how the larger nations gave to the smaller colonies. The nations
built them roads, canals, and railways. Showed them the telegraph, newspaper, established schools
for them, gave them the blessing of their civilization, and overall made them economized. They
were part of modern culture after this occurred. Another positive effect is seen in document
three called "Colonial Governments and Missionaries. " It shows how the colonial governments
introduced improved medical care, and better methods of sanitation. There were new crops; tools
and farming methods, which helped, increase food production. These changes meant less death to
smaller colonies, and overall improve the state of living. They now could live longer and have
better sanitation compared to the earlier imperialism.
