The world economy keeps crashing with many incidence of inflation. What is happening at the moment is a clear indication of a world that has failed the minority. Although the underdeveloped countries could partly be blamed for the high inflation that exists in their respective economies. Would things turn around for good if underdeveloped countries start to add value to their natural resources themselves without selling to the countries with good economy?
Doing so is like making their country worse and worse. The subsistence economy has been undervalued for a long time and it's the worst strategy I've ever known. because an economy without trade with foreign countries will be outdated, the demand will also be significantly reduced. For example, you are holding gold and everyone has a lot of gold for a long time and no one wants to buy gold, so does gold mean anything for you?
so we should have a good trade with foreign countries. That is the way to help a country develop the best.
