Why only those?

need better leadership role models to show them that education and hard work

Compulsory education in the US is straddled with numerous problems. Underfunding is maybe the biggest one. The fact that schools need to be converted into bullet proof bunkers doesn't help. Standardized tests are not a foolproof way to assess people's aptitudes. The curriculum in some states leaves a lot to be desired. A defective system cannot produce perfect students. And we're not even talking about the insane for-profit higher education system that gives people debt for life. The system produces undereducated leadership role models. The good people tend to find other areas to work in. You cannot demand new role models without a complete, well-funded overhaul of the entire education system.

Hard work can be helpful to get ahead in life. But it's no guarantor of success. It's more luck or inherited wealth that get you ahead. You seem to adhere to the good old American dream idea, rags to riches stuff. It's a mirage. Like the melting pot theory or manifest destiny it deserves to be deposited on the trash heap of history. There was probably more truth to the dream when rent/mortgage was a fifth of your average paycheck when it's now most of your average paycheck. That is if you still have a home. Times have changed, ideas are still catching up.

— not violence, promiscuity, and criminality — are the right ways to get ahead.

Violence? Agreed. Crime? Also agreed. Promiscuity? You'd have to define that first. And I have an inkling I may not agree with you once you have.

Fundamentally, you could make a caveat even for violence and crime under certain circumstances. One man's terrorist is another man's freedom fighter. To the Brits George Washington was a violent criminal. Violence is baked into the birth of a nation, along with the prolonged history of slavery and segregation.

I also think that former criminals can be valuable role models. It depends on many factors, e.g. have they paid what we call the debt to society? Have they atoned? Etc. But if I'm not mistaken you're looking more at financial fraud and maybe sexual misconduct - don't have a clue why those two popped up first in my head - and I would say that disqualifies perpetrators from being leadership role models. People who vote for people like that to get into positions of power anyway are a real thorn in my sight as well.

So I find bits of your statement that I can warm up to. Overall, I think it's a bit populist for my taste. I disagree with some of the assumptions I think you've made. And it does nothing to address any underlying problems as I see them.
