Answer: The reasons and roots cause of the gap is since the colonization of the Southern world regions by Europe over the past several centuries. This colonization occurred at different times in different parts of the world, as did decolonization.
Explanation:
Because people can learn from other people, in both in failures and in successes. The founding fathers of the United States took after the Roman republic in modeling after there government. This is why the United States Congress is structured in the same manner as the Roman Congress. Versus the rectangular or roundtable types of congresses that are seen in European countries.
They also took after the Romans on the idea of a republic being comprised of people elected to represent them. These people are also meant to be changed out on a regular basis. And that the public was in control of who was calling the shots on their behalf.
The main reason why the United States largely shied away from imperialism prior to 1890 was because it was still a relatively "fragile" nation with a host of its own issues to work out--such as the slavery issue that eventually led to the devastating Civil War.
It increases as they need to ship supplies to the army for medical uses or ammo such like. They need to rapidly produce weapons and ammo so that they can continue to fight on. Medicine such as penicillin was mass produced as it stopped infection rate so the mass production of that drug helped in ww2
Really hope this helps :)
