Getting a higher education is one thing, call me when he has published multiple peer-reviewed studies in any field and I just might take his opinions in said field to heart.

Yes this is very true. IQ is not the same as EQ, and neither are quite the same as "wisdom". The latter comes from evaluated experiences - as in, if you fail to learn from your own mistakes then you will simply get dumber as you age, whereas if you seek out knowledge & learning & evaluate the mistakes of others, then the trajectory of your life will make you SMARTER as you age (up to a point ofc).

Truthfully, the only way to spot a counterfeit is to know the real thing so extremely well that nobody can pull a fast one on you.

Speaking of, don't forget: GWB (the 2nd Bush president) only graduated Yale b/c his father donated a massive amount of $$$$ to the school - his grades (that he had sealed but at some point got leaked) reveal that he flunked out on his own merits. So even "educated" does not mean "educated" if you catch my drift.

As far as a "guarantee" though... nothing is every truly guaranteed, so that might be asking too much. Still, it's a good reminder to look at someone's character - did someone get rich merely b/c of accidents, or b/c they truly deserved it. Though, do any of the recently rich truly deserve it? Bezos who won't let workers pee (even pregnant mothers), Musk for taking a truly fantastic idea and turning into something that literally kills people, and Zuckerberg who... (shudder), just not even going to go there.
