The problem with the "billionaires must be geniuses" is that many people think that wealth must be somehow proportional to intellect, i.e. the more money = the cleverer they must have been to earn it.
Many of the billionaires are just "not-thick" and were just plain lucky to be in the right place at the right time and had 4 or 5 consecutive bets come in. There are a whole load of cleverer people who made millions but didn't get the luck to convert this into billions.
