Actually have come to understand the fact that when ever dollar increases it may likely cause the depreciation of other currencies in underdeveloped countries. Particularly this might make this underdeveloped countries to be very poor. It can also make them not to engage in the global market of trading, because their currencies can not meet up to this increase in dollar. I think it’s really a global issue that needs to be addressed in order to help this underdeveloped countries.
Dollars did not increase in any way since it's not operating its own market; it's a US currency. The reason why the dollar affects the currency of undeveloped countries is because if a country is not able to produce what they are using, they import things for their citizens to use. You can see that the traders of those items will be paying in dollars before they can be able to import those things since dollars are used in the US and most of those things are produced in the US, so from there you will see that those undeveloped country currencies will be depreciating; they will not get any value again, and from there inflation will occur.
Underdeveloped countries are full of corruption and nepotism, so the countries have no chance to changes. There are many great people in underdeveloped countries, but if those people doesn't have any relation of benefit for the civil servants, they won't support you or they will try to make you not able to show your potential because they're worried if you can take their sits.
Not even the issue of corruption: any country that cannot produce items for themselves will face this kind of situation because their currency will not be valued in any way, so the dollar will be ahead of their local currency since they use the dollar to purchase things and sell them. Although I understand when you said they don’t allow people with skills to show themselves so they won’t take another person's position, things like this happen, but when it comes to things like this, for me, those things like skills also work since if the citizens are able to produce them, the country won’t suffer from these kinds of conditions.
