Reasons why Brazil is the best country in the world My opinion as a Brazilian, born in the heart of the country, is that Brazil is the best country in the world. ❤ ❤ The prettiest, the happiest, the most receptive, the happiest. It is the country of diversity. Musical diversity, cultural diversity. Brazilians are black, white, mulatto, blond, dark, red, short, tall... And even with so many problems of corruption, lack of sanitation, congestion in the streets, airports, problems in public schools, public health, street safety, and so many others, Brazil manages to be the country it is. People manage to abstract these problems and simply be happy.
