In the US, not working was the top reason for a higher amount of loneliness among middle-aged adults, while in other countries it resulted in more loneliness among older adults.
I mean... This is America...
It cost money to do pretty much anything, if you don't work then our "safety nets" don't give you enough to live.
Hell, 60% of Americans don't make enough to live. And unemployment isn't up to 60% yet.
If every social interaction includes some kind of price tag, the majority of Americans can't afford to pay it, no wonder people are lonely
