America treated its allies and enemies from World War 2 very differently than African countries when it comes to aid.
America made sure the money to Germany, Japan, Korea, was used to build their infrastructure. That helped give work to 1000s if not millions of low skilled and unskilled people in those countries and gave them a working class livable wage. America also protected them militarily so that they didn't have to spend much if any of their GNP on military spending. Europe had NATO which is the US primarily. Japan and Korea got US military bases. Lastly, they allowed Japan and Korea and Germany to a large extent to sell their products to America without hindrance. And didn't force them to accept bad trade deals. Japan and Korea specifically as well as Germany to a fairly big degree to have protectionist trade policies. It was impossible to sell a Ford or Chrysler car in (then West) Germany, South Korea or Japan because the tariffs were astronomical and made it a non starter. America didn' trip on it. So the Koreans only had Korean car options, Japanese with their domestic options only and Germany the same.
These countries were also left alone in terms of government intervention. Many people don't know this but South Korea had a military dictatorship for many, many years that didn't end till the 80s, for example.
With Africa and also to a large extent the Caribbean, the US didn't aid these Black areas the same. They used aid to make them dependent. Sometimes on TV you see news in Africa and some kid is wearing a University of Miami t shirt or a Converse t shirt. Why? The US forces these countries to accept our used clothing. The Goodwill quality clothing. There are ship containers full of it and these countries can't build their own domestic clothing market because the US threatens them with sanctions. As we know the US actively removes the best leaders. And have done so for decades since these Black countries became independent.
In a nutshell, the US (and Europe after they were developed post WW2) targeted Africa and the Caribbean to be enslaved economically and mired in debt. An American for decades was head of or high up in the IMF or World Bank. The US, Japan and Europe run these organizations. They are not independent. They loan Black countries with terms that makes sure they are dependent on them and they can't pay it back. Germany was given money in the Marshall Plan.
The only way I think Africa should accept any money is if its in a similar Marshall Plan format, where its purpose is to build up infrastructure: build roads, bridges, tunnels, providing jobs to the poorest and the money is not paid back. That will never happen. White Supremacy won't allow it to happen.
All black run countries, especially the Caribbean should have done what the Philippines and possibly Mexico (I have read conflicting articles) has done, where foreigners can't buy raw land. They can buy in a condo which has air rights but not the land the condo is on in Philippines. The Caribbean has possibly the best beach front properties and views of any area globally. Worst thing Bahamas, Jamaica, and other tourist areas could have done was allowing US companies like Hilton, etc to own their best beach front land. Lease it but not sell, they need to come to you because of demand. Just one of several things the Caribbean got wrong.
So, what then? They need to get on code, put aside tribal rivalries, see white folks for who they are. Get the corrupt mofos out the paint, link up with Blacks in the diaspora. When we (American, British, and to some extent Caribbean blacks who travel) go to the motherland its respectful. We see it as 'home'. Africa and the Caribbean needs to see American FBA as family when we migrate to America.
