Here's some more sage wisdom: the average human has approximately one testicle. Except not, right? Because that's not how numbers work. So, it doesn't matter if, say, only 4% of the people you interact with are unlucky and 96% aren't. This is not an engineering problem. If you do meet someone who is (or was) unlucky, and you have an interaction with them like this, then even though they're in the 4%, their circumstances are still 100% at odds with your assumption.
For what it's worth, congrats on what you did. I'm in a similar position and I completely agree that for the majority of people here it wouldn't take anything beyond stopping making bad choices.
The score is just some meaningless internet dick measuring, so why care at all?
I am not saying "everyone can make hundreds of thousands of dollars per year if they stop being dumb."
What I am trying to say is "Most people can avoid being massively in debt by making better spending decisions."
