yes higher probability when you have rich white people vouch for you

yes, going where they are helps, be interesting, act like them, do some lines (optional) - if that doesn't come natural because you pride yourself in conforming to a different subculture - then try this perspective:

this same strategy works in every country.

get someone that looks like the power group in those countries. you aren't going to expand your market in China and simultaneously worry about disenfranchised minority groups in China, you're going to go in China guns blazing with a local influencer that's a registered party member.

You aren't going to expand into former Soviet countries, digging for disenfranchised minority groups to be on your billboard just to show how much progress has been made, you are going to go there for sales and support.

It's a mistake to treat America and the rest of the West differently.

After you already are comfortable, you can consider trying to inspire people that look like you or have the same background as you. But before then, its just a distraction when there is a path of less resistance.
