You're responding to an aggregate statistic with an anecdote. I too did not graduate high school, but now have an advanced degree and a high paying job. Claiming that that invalidates the notion of privilege is silly.
Still, he literally said "do skilled work and spend your money wisely", the former implying that he focused on developing his skills, and the latter implying that he didn't live beyond his means. Hard to characterize either as some sort of undue "privilege".
I didn’t graduate high school, my dad waited on tables to raise me. Get out of here with your privilege crap.
