I believe the answer is: African Americans were receiving equal pay for their work so they also wanted equality in political life and other areas.
Their effort to demand equality in these area lead to the creation of the Civil Rights act in 1964. This law banned all people and organizations in united states to conduct discriminatory treatment based on colour of the skin , racial background religion, gender , or national origin.
The British had tons of internal and domestic problems to face their own, so basically from the beginning (early 1600's) they entered into a period of salutary neglect (where they didn't enforce their own laws)
Hope this helps!
