> It's infuriating and unjust that the wealthy have more rights.
No they don't have more rights. There is nothing preventing you from creating your own private company and sell equities only to poor people.
It's like people having a party and not inviting you. You can be frustrated about it, but please don't start whining about them violating your rights or anything. Just as people have the right not to invite you to their daughter's birthday party, they have the right not to do business with you.
Doing things in private association is a right everybody has, regardless of wealth.
