This is a never ending nonsense statement.
Sure, it *literally* isn't the only way to acquire a career with a decent income BUT Black men aren't flooding apprenticeship and trade programs in the absence of a college education - they're stuck with menial jobs, working for less than minimum wage, involved in illicit activities to get income, or on the lower-rung of corporate America *without* the completed college education.
If you ask young Black men why they're attending they tend to give the same responses: 1) college "isn't for them" (bullshyt); 2) college isn't with it (bullshyt); 3) they want to be entrepreneurs and college won't help them succeed in that (bullshyt); or 4) they hated school. The last one is a mixed bag, it can be legitimate (they dealt with prejudice, targeting, or were in a poorly supported school), illegitimate (they weren't trying, got in trouble for things within their control) or something harder to pin down (failure to accommodate disability, parental failure to prepare them, ill-suited school curriculum).
The problem is largely social reinforcement and creating/sustaining a pipeline.
