Yes to all of those questions. If people can't imaginatively project themselves into winning circumstances, then they become despondent because their escapist fantasies (which some people take seriously enough to make into real accomplishments) are now dashed forever.

This is something technologists and scientists largely don't get. People are always 'look at how many material comforts and and entertainment options you have now, are you not entertained?' Likewise scientists are often 'I spent years of my life and a small fortune learning to be expert about this obscure thing that you'll never be able to experience directly, isn't it awesome?' And people are entertained and they are awed - to an extent.

But they're also sad because the more the world is codified and quantified and parceled out for ownership. there are no new countries to discover, no more large exotic fauna to find, we're constantly reminded that religion and magic are illusory and that the economics of capitalism are inevitable, so there's nothing to look forward to in life beyond being ground up in the gears of the consumerist machine.

That's why there are so many movies about superheroes and rebellious people with psychic powers and so on. People need something to believe in other than the ultimately extremely boring prospect of working, raising a family, and retiring. They want 'adventure and excitement and really wild things.' This is why we now have an administration whose stated Big Idea is the construction of a giant wall* because at least that sounds like a project you could get absorbed in for its own sake, whereas preserving the earth for future generations feels nice but is never really done and so can't deliver any sense of adventure or accomplishment for more than a few people with the resources to get a PhD.

It's also why countries (soo to include the US) are apprehensive of war but develop tremendous enthusiasm for it once it's declared, because it provides a massive uncertainty that offers the possibility for drastic change, heroism, betrayal, defeat, victory and so on. I don't know how to articulate this better than by saying that capitalism is boring for most people, in the same way that if you are playing Monopoly there's a point at which you realize who's going to win and all the fun goes out of the game for everyone else in direct proportion to their declining odds of success.

* If you don't mind losing 2 hours on a bad movie. go watch Pacific Rim, a stupid science-fiction romp about giant robots vs giant aliens. It's stupid in the sense of not really caring about the science at all to the point o making jokes about how stupid it is - at one critical moment, someone 'solves' the problem of The System collapsing due to 3v1l h4x0rs but remembering that they have a nuclear-powered robot and exclaiming 'It's not digital! It's nuclear- it's analog!!'. The very badness of this movie makes it worth studying because the psychological symbolism is so thinly disguised. Almost all alien invasion movies are vehicles for conservative ideology, and it's not an accident that a political campaign for building a giant wall was anticipated by various movies involving the construction of giant walls.
