To every good thing there is a bad effect. The effect of helping third nations to get in debt is hate. This hate accumulates and the result will be similar to the bubble exodus. This the modus operandi of capitalism - whoever holds the bag last will get in trouble.

There might be some few good cases but the greater part of history just serves my pessimistic view. All the empires claimed to help less developed nations to become "better". Only for some strange reason the latter didn't want this help until persuaded with military force.
