i think that this ratio exists because of racism. still till this day racism and discrimination exists and it's practiced by many people. white people underestimate the ability of a colered person just because of the color of their skin or maybe because of their background story. they feel that if a black person didnt graduate from college that they dont have the potential for a real job and for responsibilities but if they know a white man that didnt graduate from college and is looking for a job they would consider his situation and i dont think thats fair because in some cases colored people have the same or even more potential than the white person.
