in history there is no nation, empire,country whatever, has gone too high above the others without exploitation of others by means of war, invasion and some other methods..
ottoman empire was a good example I think..
although many of my citizens dont accept,
ottoman economic system was primarily dependant on exploitation of other countries\nations by means of war..
every spring they go for invasion\war as the treasury became empty ..because its system was not dependant on production even on agriculture..
but as most of you know expeditions on American lands changed many things , adding also the Renaissance age and after industrial revolution , brought it to the end..
now in this century
there is no chance for a poor country to exploit others and fill its treasury ..
only chance is to work till death and utilize technology as much as possible.. and use the available resources
very carefuly without wasting anything for luxury..
so the recipe for poor countries are already fixed..
for poor countries with communist economic planning prooved to show the maximum growth rates..
(you can check the net , various examples exist)
also giving an example from my country , 10 years of growth from 1929 to 1939 (despite the global economic crysis) was enormous compared to the later years where the system shifted to the capitalist planning model..
I dont go in the details of numbers or different examples as its tedious but the prooven examples are there, applied and being succesful..
