Another way to look at it (especially for those allergic to the idea that privilege may apply to their own outcome) is that ambition, risk taking, and entrepreneurship are evenly distributed across all socioeconomic classes, or close to it.
It's just that some distinct socioeconomic classes have the capability of failing and retrying very quickly, due to moneyed resources.
Contrast that to the person without assets or access to capital, they save up, take a chance, fail, and now have to wait maybe 10 years or more to get to the same place with jobs. And with time, there is error introduced, divergent paths, life changing events, or simply competing priorities as the years keep going by. Alternatively, everyone else in their similar situation rationally decides not to bother, a good network for them is one that exposes them to basic personal finance gurus on odd forums and youtube, who give them generic advice that works for a broad population.
On the concept of privilege, there is no parade and red carpet that gets rolled out, you just wake up one day and realize that you don't have to apply for jobs to maintain food and shelter, and that your bank account also has enough to make that seed investment or hire developers. So, if you're willing to play your cards, you play them. Enough people are willing to and their successes wind up outnumbering the poorer people that want to play tech entreprenuer.
