well, I actually love world collapsing it is a lot of fun to explore ruins, abandoned buildings, creepy hospitals especially if done with some cute girl :)
It so all so relaxing and effortless nothing to worry about, just enjoy leftovers of the previous glory and effort of people who made all that.

And i also hate all that growing economy when things are being built non stop when everyone is working like some and without a minute of rest making some shit covering all earth with fences where you can't enter anymore unless you pay and work hard just to maintain your pathetic existence.

However I do not want people disappear completely. That woud be boring I would love everyone stop working and just enjoying easy life making just the minimal effort to stay alive.
don't buy new car run your old suit to the ground instead, until it breaks in half
It woud be interesting if something happened and like 90% of people disappeared, leaving all their stuff empty houses cars factories, there woud be so much of stuff around that nobody of remaining people would need to do any work anymore.
in that case when you walk around instead of seeing everybody as enemy you would be happy to see someone and have some fun together.

all that is already happening population is on decline, but sadly I will not be able to benefit from it because remaining people are actively destroying everything what left.
