There are three ideas core to your comment that are, at best, controversial: marriage as a predictor of success, French-born developers are lazy, and wealth/social exclusion having no role in whether "having the right parents" applies. Also I'd love to see a deeper analysis of your "86% of billionaires" comment. Usually what happens is we discover that "self-made" millionaires grew up in quite affluent circumstances, perhaps not with millionaire parents, but with parents who earned a sufficient income to themselves retire as millionaires. That is to say, they aren't "self-made". It isn't meaningful to compare their accumulation of wealth to the struggles of those born in less favorable circumstances. There are no "self-made" billionaires. Or very, very few (WhatsApp founder Jan Koum is literally the only one I can think of who comes close). Every single high-profile billionaire today--Gates, Buffet, Zuckerberg, Bezos, Musk, etc.--came from a family with substantial financial means and social connections.
