I have the same postulate but the complete opposite reaction, if the future is going to suck I better do the right choices with my money while it's not so bad rather than blowing all of it on useless things.
Rent eats up half your take home pay and while you're not terrible with money, you are also not super frugal. So you are ultimately saving a few thousand a year. At this point road to being rich is half a century away and pretty narrow. You better not get sick, or have to take care of an injured family member, or scammed, or divorced, or laid off for an extended period of time. And all around you is a media, political, and social ecosystem telling you the good times are over.
It makes sense why some people just decide to lie-flat.
