>. It’s not shocking that Country and Sector are important variables but “founding_year” is intriguing. It could mean that it may be getting easier or harder to build a sustainable business. It should be pretty obvious that LUCK is a huge factor. It's that age old saying... how does it go? "Success is when preparation meets opportunity." Bill Gates got rich because he was the right guy, at the right time, with the right (completely unfinished vaporware) product when IBM needed an OS. Most of the new billionaires are techies. Techies that happened simply because the world became tech oriented. Surprising... nobody. There are entire billionaire families from previous "Rushes". The gold rush, oil rushes, wall street, RAIL ROAD TYCOONS, etc. There is no scientific way to guarantee billion-dollar wealth, only correlations. And the only data I see from the article is: 1) There's more than one way to skin a cat. Some dropped out, some got Ph'ds, many stayed in the middle. That doesn't matter. Wherever you are now, you can start working. 2) Luck matters. You can be successful but the chances of you exploding is fractions of a fraction.
