I don't think "fooled by randomness" makes sense, because it presumes its conclusion. I do not believe that Warren Buffett is just a random guy who happens to always make the right stock picks. He makes the right stock picks not out of randomness but out of the opposite of randomness. (For instance he makes very few picks a decade.) While the competition to Buffett are often people who are much closer to "Random" (or would be better if they were random).

The same thing can be said for a bunch of MBAs. It is not whether they are rich or not (which can be a factor of having been born into money or not) but whether they can make it rain.

Sure, some will get lucky. But when you have a field of 100, and of those 100, 20 "got lucky" and made a pile of money once, and 1 of them might be poor, but made a small pile of money every quarter doing several different things... it is the consistency of the last guy-- the rainmaker-- that is appealing. Even if his net worth is smaller than the smallest of the 20 who "got lucky" or the dozens who may have started out rich.

So, it is his actions as a process that speak to his qualities, not the size of his wallet.

I think this is what the poster is saying.
