This was just another American cool-aid. The strategy was this: cultivate a hyper-consumerist, greedy and gluttonous population at home. Invite other countries to export and trade with the US. Build a dependency from which countries can't unwind themselves out of. Enslave the world and rule over them. Continue the aforementioned strategy while dispensing other cool-aids like "trade prevents war".
Yet, it seems like the enslaved nations still haven't gotten the memo.
