This is a good explanation of one of the reasons that expecting everyone to just "work together, we're all in the same boat" is not realistic nor a useful approach in this context. Because we are really not all in the same boat. We have different backgrounds, perspectives, different goals and time horizons, different investment views and objectives, etc.
To get people working together toward a common goal requires an economic system where working together is viewed as rewarded, even by people with a short term time horizon and longer term skepticism. Because there will always be such people and we can't even say objectively that they are wrong.
So the economic incentives need to be direct and short term, not relying on a particular long term vision that not everyone shares. Only by getting those incentives right (or at least, more right than now) can we coordinate a large group of people with diverse perspectives and goals to actually work together, not because they want to or are told to, but because their individual self interest unambiguously depends on them doing so.
Yeah diverse perspectives play a big role in individual participation level. I was listening to @lukestokes during the video where he mentions the idea of volunteerism. People need to come forward to take up responsibility. The system is not perfect but we are trying to approach the idea of just rewards.
Greater the voluntary participation the more is the long term reward.
There is also the fact that reward is not just a one time payment, it's a stake in the system which incentivizes further participation.
