The point of the meme is to compare the UK situation with the US situation in regards to the black community.
Problems within the US black community are traditionally blamed on factors such as slavery, segregation laws and systemic racism-- yet when you take any other black community which existed without those issues, the results are the same.
Ergo, the cause of issues in the black community are not the ones being claimed.
