It depends on what happens with the doom, first, no? What happens if the objective world is damaged so severely by climate change, and the social world takes not only the effects of that but the increase of poverty, social instability, and the increase of being a "have not" in a system that demands you be a "have?" This isn't something that will be defined by the next president, but it will continue to bloom and expand as time goes on, and so long as our heads are in the sand, we're not being sincere enough.
Projections for even the labor front look doomy for the next few decades if technological disruption expands - when that second machine age will fully make a dent is in the air, but many argue this century, and I personally lack a true ballpark idea - but that alone is enough social doom that a doomy scenario happens. I state this as the answer to the problem is merely more jobs, or even worse, a job guarantee for all, which fails to see the innate problem. Mix that with a dying world, and that's quite a cocktail. That's perhaps the worst of all possible scenarios, in merely a first world sense.
Of course, this means we should try and make people more aware of this, and of course demand more from the people we elect. Unfortunately so, there's only one candidate who's mentioned the climate as the worst problem the world faces - and it is - but the labor issue has been ignored by everybody. It's a major ghost in the room regarding human suffering and our ideas making bedsores that only risks getting worse for some, not better.
But remember this: there are literally parts of America today that can genuinely be compared as third world conditions. The climate, be it the real one or the one we project, is already not doing these people any favors, and seems to have no plans in changing. We should be doing a hell of lot more than what we are doing now, but we are led by the least among us.
No one really knows the long term impact of technological disruption. There has been plenty of technological disruption in the past where jobs were completely eliminated from the economy, but new ones sprang up from the due to those technological disruption. One can argue that this time will be different because machines will be talking over jobs, but that does not necessarily mean that new ones will not be created based on that change and does not mean that not enough job will be created just because you or I can't think what all of those jobs will be.
