One cause of socio-economic inequality in the USA is discrimination, which is any kind of unfair treatment of individuals or groups. This is because some groups in society, such as women and ethnic minorities have in the past and continue to experience unfair treatment in education, employment or even law. For example, the poverty rate for Black Americans in 2017 was 21% the highest in all of any group in the USA. This means that the racist laws that once existed in the USA have put so many African Americans in a poverty trap even today.
