Younger people generally tend to have simpler models of the world around them, but those models often have different sets of assumptions at their bases from older people, and there is no way that any group thinks, all individuals think differently, so every group has a distribution of thoughts/models of reality; so there is some utility in the question, and the group think assumption behind it is a big part of the problem we currently have.
If we are to solve climate change and all the other serious issues that we currently have, then individuals must be willing to think for themselves, and to challenge the assumptions of the past (respectfully), to take independent action (in a manner that respects the lives and liberties of others, and the integrity of the ecosystems around us) and to be able to live with diversity.
Individuals must get as comfortable as they can with change (all levels).
What we see in society today, is a competitive scarcity based economic system driving people into new levels of anxiety, which decreases their ability to handle complexity, and thus tends to drive them back towards old models from cultural pasts.
What we need is a cooperative based system that meets the reasonable needs of everyone (everywhere on the planet) for both security and freedom, while respecting the complex boundaries necessary to maintain cultures, technologies and ecologies. We cannot get there by going backwards, as such a thing has not yet existed at scale.
We must go forward, we must do so with trust, we must do so with eyes open for the possibility of cheating strategies present (all levels, any concept set can be weaponised to distort sensemaking – so distributed trust networks, and a willingness to test things for oneself are essential components of stability), and we must do so in a fundamentally cooperative mindset, if we are to have any significant probability of having a place we would like our children (or their children….) to live in.
Competitive systems cannot deliver stability. The mathematics of that are beyond any shadow of reasonable doubt.
We are the most cooperative species on the planet, and we can certainly compete if the context demands it of us.
We are complex – each and every one of us, deeply more complex that most stories give any real indication of.
The technology to support global cooperation and global abundance of all reasonable necessities is relatively easy, we have all the automated systems we need, what we currently lack is sufficient levels of awareness generally.
Most people are still captured by some version of faith or loyalty or patriotism that has been turned from the virtue it can be if used in the service of all, to being a weapon in the service of some subgroup (essential a cancer on body of humanity).
The only real security for any of us exists in acknowledging that for all our many and cherished differences, we are all far more alike than we are different.
We all need to look deeply within ourselves for such things, there will be many levels of them hiding there. Awareness is the only reasonable response. The price of freedom is eternal vigilance.
