are we psychologically prepared for this era where resources across board are no longer in abundant and our global population is growing fast?
I think part of the issue is that we sometimes romanticize the past, so while many things were indeed cheaper, wages were lower, opportunities were more limited in some sectors and then access to information was nowhere near what it is today. What has changed significantly is the level of competition. More people now are chasing the same houses, jobs and resources, so the scarcity feels much more visible than it did before.
As for whether we're psychologically prepared, I would say not entirely, like alot of persons still operate with the mindset that opportunities will always be plentiful and that economic growth alone will solve most problems. So the reality is that a growing population and finite resources mean individuals, businesses and governments will need to become more efficient, adaptable and strategic than ever before.
