I think government should be the one who oversees the state economy condition. Managing the economic status of its country on its own.
As governments can look after its country on its own then the nation can be independent. They won’t need help of any other nation. There are many such nations whose government outlook their countries economic status on its own, due to it they are well developed. For example: Germany after world war2 they have faced huge loss, all the places were damaged. Their government and citizens stood together and re-build all the damaged parts and today they are one of the biggest countries in the world, they did not even take help from any other nation their government were there for them.
If government oversees its nation on its own, then the nation might be more secure. As if other country could help a poor nation, then they might take advantage of poverty-stricken nation. The citizens living there, and the country could face a huge loss. As an act of develop, they could take away many things. Leaders, the one who is responsible for taking care of the country should be able to manage all the things. For example: my country is Nepal, which is being helped by many other nations, due to it we are facing a lot of problems, such as: security, governmental problems, bordar problems were people living beside of bordar being in violent act with other nations. There are a lot of disadvantages, because of it I would prefer administration to be responsible on its own for any kind of economy related problems.
To conclude, for security of nation, nature, history, citizens and the cultures government should be responsible. Utilizing the products nation gives us in a better way government could develop the country. Rather than being independent towards other we should it by ourselves.
