They forgot the most important financial mistake of all to avoid, being born into a poor family.
You mean like JD Vance??
There’s nothing wrong with being poor. The mistake is staying poor.
I was born into a periodically homeless family of drug addicts.
Other than my complete contempt for drug users, I’m fine and easily in both the top .1% of income and wealth.
The circumstance of my birth is irrelevant

Ive known people from poor families who became wealthy and successful.
Even a poor person can retire comfortably. If they are poor they are used to living on a meager income thus they wont need much in their retirement years. Beyond social security.
The key is to save at least 10-15% of your salary for 40 years or so.
