A couple of things here that I really like. I really, really like the idea of random selection. I'm not so sure it transfers well to national issues, but at a state level, certainly. I think it would work just fine, so long as selection was truly random.
Hate speech? We have tipped completely over trying to satisfy everyone. The minorities MUST be protected, but in all actuality, so must the majority. I believe this issue will ultimately settle itself, but the interim could be gruesome.
Possibly the problem is that the USA has too few people in control of certain aspects of the economy and legislation. I believe that one way to deal with this is for each municipality to issue its own cryptocurrency. This is an incentive for local businesses and less so for large corporation such as Walmart which tend to siphon equity out of regions. If a currency can only be spent locally it will have a high velocity of money.
As far as minorities, they shouldn't have any rights superior to individuals (the smallest minority). Instead of having affirmative action enabling specific minorities to have precedence in attaining higher education, enough seats should be available to allow everyone to go to school. If poor people cannot afford it, the prices should be subsidized for everyone. For instance it costs around $13,000 CAD ($10,000 USD) for a Canadian student to go to school. This covers everything including housing, food, tuition etc. This is almost attainable for all people. Meanwhile our provincial government has been running a pilot project to introduce universal basic income. It would probably be about $1000 per person. Immediately this puts university education within the grasp of everyone. Even the poorest should be able to earn enough during the summer semester to cover any shortfall.
As I said, satisfying the rights of the individual is a far equitable solution than a specific group.
