Why is economic problem with solution is not enough?

The west is economically gifted by nature and most countries of the world are not economically gifted, the world's social problem is financially related and economies alone cannot solve the world's financial problems. What is the job of the world bank and IMF? Pride is basically the main problem of the world and we should all humble ourselves at all times as the God of the universe has with held the solution to the world's overall problems. The world is long overdue for a single global currency which will serve as the world's reserve currency under a new world financial institution or if the world bank and IMF are ready to turn their services to the world then the single currency will serve with the true bank to solve all financial problems all over the world.................there is no other way out.........
