You mention at lot of valid concerns here, but I also think you're mentioning an aspect of reality that human beings haven't developed a workaround for yet. It's kind of like saying predators still hunt prey. It's part of nature that those who have want more. We just happened to notice a big difference between those who have $10 and gain $0.10 and those who have $1,000,000 and gain $10,000. The math may be the same, but it feels different. Also, whoever has money can more easily make more money. Again, no way around this unless we enforce systems which will ultimately cause investors to leave and destroy the value in the platform. Generosity can't be demanded. It has to be learned and appreciated through life experience. There are more options than buying up votes, but building relationships with influential people and providing value can't be avoided.
If you have suggestions on how things could be improved, I'm listening. A lot of study of game theory went into this platform and continues to drive its economics. If we ignore that and suggest changes without understanding, we can actually threaten what we have here.
