Even aside from the obvious point that the outcome of this gamble is luck, there's another more subtle point that I think is more important: For people will significant wealth and resources, it is very cheap to take gambles like this. For some people, dropping $10k into some high-risk gamble is just a bit of fun, but for other people that's their entire savings; and for other other people - they'd never be able to afford to do that even if they were starving themselves to save money.
How do people get into that kind of position of privilege and power in the first place? ... the luck of where they were born.
