Okay, here is a twist: How much do poor people spend on lottery/gambling activity? How much is that proportionally to their income?
From looking at small casinos, betting shops, lottery and online sites (sports) it seems that poor people are risk takers. One reason, in my opinion, is that they have little to lose. They also have really shitty lives and are looking for an escape.
If you were starting a startup alone in Bangladesh vs. starting solo with YC in SF. Building a remote-based startup that sell SaaS online for clients all over the world. Location of clients is everywhere.
Technically, the playing-field is equal. You start a C-Corp from Bangladesh and trade your business. But which one do you think will make it? Which one do you think will raise funding? Or succeed if both do not raise funds?
You live your life trying the optimize a problem. There is a number of steps that if you take, carefully, you'll become rich in some duration of time. You don't know these steps, so you keep searching. You know gradient descent. Life is like that, if you are moving successfully down, you are probably on the right track and so you keep moving on that direction.
However, you start stochastically on a random location and keep trying to find a path that leads somewhere. That's where YC comes in. They help you reduce the surface area of your search. You are less likely to land somewhere futile.
What poor people are missing is discovery of this surface area. It is a very complicated problem for them and they lack resources and education to optimize the problem.
They are hoping that this lottery ticket will help land them directly on the optimized spot. Their lack of understanding of why this doesn't work explain why they can't navigate the surface area.
