Except that your narrative is exactly trying to paint it as "only rich people get to succeed", which will lead to the "not rich" to give up trying, which will only make things worse.
You probably think you're doing justice to the world, but you're actually doing the opposite.
The real successful people succeed DESPITE their perils and in many cases BECAUSE OF their perils, and these people should be encouraged to pour all their passion into whatever they want to achieve and succeed. Instead I see people like you always saying "doesn't matter how hard you try, the world is fucked up because only the rich get richer, so don't tell people to work hard, it's just exploitation". That probably makes you feel better about being "woke", but your argument does nothing but convincing people to give up.
These people who come from bad background, when they do succeed, they they give back to the alienated community they came from. These are the people who actually make progress with inequality, not some guy on HN and Medium.com bitching about how the world is unfair and all the successful companies are shit because of that.
Your narrative only gives people excuse to complain and get distracted from actually building valuable things.
Like I said, the world IS unfair, and nothing will stop it from being unfair for unforeseeable future. The most efficient way to make sure we get out of this situation is to encourage the alienated people to succeed instead of getting them into "me vs. you" mindset, because that mindset is a loser mindset which only leads to wannabe activism, instead of actually creating something valuable.
If you want to prove me wrong, just tell me a single successful person who built a valuable business or product, who spent most of their time playing gender/sex/income/inequality/whatever activist. Unless your business itself is a consulting business to sell to these classes, I have never seen one.
