Your comment reminds me of the video where they ask white people in Berkeley, CA if voter id laws are racist. They say yes of course they’re racist because African Americans don’t have id as often, don’t have as much access to the internet, don’t know where the DMV is, etc.
Then they go to Harlem to ask people what they think of those comments.
As for your claims themselves, In 3 months I studied 350 hours to pass the hardest test in finance while I was married, had three young children and worked full time. Nobody has time to do the things required to advance your career. You have to make the time.
For years, I also recruited and mentored students from an inner city bootcamp near me where the students spend 80-90 hours per week for 12 weeks learning software engineering. The vast majority of students are minority and there is fierce competition to hire graduates by local companies.
