There is a major reason this is happening, and it's actually connected to the question "if God is all powerful, all knowing, and loves us, why does he let bad things happen to us?", so I'll explain it in that way.

Think of the sum of human experience on a 2D plot line, with the best possible things occurring on the far left side (not politically aligned), and the worst possible things on the far right side, with a smooth transition from one to the other, with neutral stuff in the middle. Humans lament the above question of God, and lets say God relents, removing the worst half of human experiences, from the far right side to the middle, only allowing people to experience from the middle to the far left.

At first, people would be grateful. Then they would get used to it. Then, probably over a few generations, they would forget it, and now believe that the worst possible things they could experience are the now perceived far right of the scale (which used to be the middle/neutral experiences). Humans then lament the question again, and again God relents, removing the worst half of human experiences again (this would only leave the far left 1/4 of human experiences).

At first, people would be grateful, then they would get used to it, then they would forget it, repeating the cycle over and over again, until people could only experience the best possible thing, forever, for everyone. This, interestingly, is often what communists push for: pure equality of experience, regardless of individual, circumstance, location, etc.

At the most basic level, humans are mortal, finite, imperfect creatures, with free will capable of affecting change around them and in themselves, and have imperfect memory. There are a few exceptions to this, but the point is that in combination with the above question, cycle, and inevitability of trying to solve it, it shows that humans are designed to suffer. Objectively, not all suffering is equal, but subjectively we all suffer relatively the same, because we forget, and lessons learned are not perfectly passed on to the following generations.

This applies almost perfectly to the current situation western civilization has put itself in. We've become so successful, and our lives so comfortable and free of the objectively worst experiences, that we're no longer grateful, we've become used to it, and we've forgotten such experiences. This has led to a great number of people lamenting smaller and smaller trivialities, not knowing that they're living in some of the most prosperous, peaceful, and best times humanity has ever known.

How can we stop this? The extreme example would be to throw such idiots into nature, forcing them to survive on their own merits, learning what is truly important, and what true suffering is. If they can survive and thrive, they can reenter society, knowing they've learned the hard lessons that many of us have forgotten. It should be noted that if we wish to prolong the collapse as long as possible, everyone should go through this experience, to learn the hard lessons so they don't forget. A less extreme tradition meant to prevent such people from popping up, we can, every day, pray and be thankful for all that we have, regardless of how basic or small, with the intention of never forgetting what we have, where we come from, and what we've learned. Other traditions could surely be thought of and implemented to prevent the forgetfulness of ourselves, retaining the hard won lessons of mother nature.

If we don't do these things, we are doomed to repeat history, unable to escape the cycle.
