I agree with this --> 'Does it even matter who becomes president? Of course not! Things are never going to change. The system is designed to keep the rich and powerful, rich and powerful. "
Don't agree with this 100% --> "They only way to have a chance at changing the system is blockchain technology" It will have a huge impact and a major player in my opinion. Any decentralizing action will help change "the system"... even using Gold and Silver (very analog) will help.
The more that any individual stops participating and switches to any decentralization where two individuals can transact voluntarily, that is where the power will be in the future. It may get ugly in the transition, but that will be because the old will be fighting for its life.
