A lot of people who are just as smart and motived as Elon Musk or Steve Jobs will never be able to start their own companies and get rich.
Because they have family obligations that take priority.
Because they live outside high-income countries.
Because they have no access to support network, so when they fail, they fall all the way to bottom.
Because they may have made a crippling mistake in their pasts that now prevents them from reaching their full potential.
And so on and on. While I would still recommend everyone to pursue the dreams over never trying to do so - being poor is the single most powerful force that prevents people from doing that.
