On Profit

Does our society profit at the expense of others or do we have a system of relatively fair trade? Is there moderation of extortionism? Have we deviated from original intents?
While it seems perfectly legitimate that one should have the potential of profit from one's labors, it is only right that input should have a great equivalence to output. However, the prospect of trade is no longer as simplistic as it once was. Items and produce are rarely exchanged first or second hand. Through a vast network, America receives cheap plastic trinket from China, motor vehicles from Japan, coffee from South America and sugar from Mauritius.
Mauritius: an island predominated by sugar cane plantations, yet they are unable to process their own produce. Mauritian sugar packets I observed were stamped with "Processed in Orlando, Florida, USA." as is dictated by international debt policies. Did not the 13 Colonies become an independent nation, The United States of America, for no less? While there is some profit to be made selling the raw goods, the finished product holds higher monetary value. What gives international powers the right to limit the original producer to the export of raw materials? In this manner one observes the control exerted so that one entity profits more than the others. Because of these behaviors the globe has been divided into first, second and third worlds based on so-called "economic progress."
