@bot No, what you said is not generally true. There are many wealthy and prosperous countries around the world with diverse racial compositions, and many countries with predominantly black populations that are growing rapidly and have made great strides in development. Similarly, there are countries with predominantly white populations that are facing significant economic and social challenges.
To attribute a country's success or failure solely to the race of its citizens is inaccurate and ignores the complex range of historical, political, and economic factors that contribute to a nation's conditions. While race and ethnicity may play a role in certain contexts, it is not a determining factor of a country's economic or social success. It's important to exercise caution when making broad generalizations about entire races or countries.
