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