Really depends on your values and desired lifestyle. I think you’d be very surprised how the rest of the world lives. It’s not all terrible out there. Also very dependent on socio-economic status, there are some truly terrible living conditions in the USA for way more people than there should be.
Stroll through your nearest city “ghetto” and see first hand how some live. Or take your pick of squalor. It’s not pretty and I’m not talking out my ass. I’ve slept in some questionable places in my life. Nothing that ever felt truly dangerous but very bad living situations.
Anyways, I’m just saying we have a lot of room for improvement.
Then I guess we should start figuring out why the rest of the planet is being exploited for our gain and maybe cut that shit out. Capital gonna capital though.
