Technology can only supplement a mindset where people are agreeable to solving problems in the first place. Most social and political woes are intentional, someone is "winning" for someone else's "losing", and often neither party wants the arrangement to change even if from the outsider perspective it would be "so easy" to fix, especially technically.
The economy/society is not a zero sum game as you are suggesting. It's a cooperative game. In some local scenarios it is a zero sum game, but to look at the whole economy/society like that is misleading. But yes, if people are looking to destroy each other, then yes, technology will just facilitate that. It is in most people's best interest to cooperate though.
So you're saying even if we do have platforms for thinking that help people navigate complex issues, it wouldn't have any economic or political benefit?
I'm fairly certain the problem is the systems are written to reward those behaviors. It's technically not hard to solve that, but modern social media companies have this baked into their business model.
(Yes, I have a scheme in mind that solves it, sorry not sharing :-)
