What is an example of the UN's success concerning the economy of a country?

Question

I have examples of humanitarian problems that UN has solved and political ones but what is an example where the revenue of a nation has increased due to the UN?

Answer 1

The UN does not  directly concern its self  with economic problems, the IMF and the world bank is responsible  for that. However the improvement in health care, family planning and solving  humanitarian problems  often leads to increased growth of the economy

Answer 2

The UN is a worthless organization.
