imagine having a bedroom couch, mind blown (okay not exactly, but I'm pretty sure even my wealthiest friends/family don't have a whole couch in their bedrooms, maybe a chair or bench...)
my dumb ass would probably sleep on it every night. I don't know what it is, I don't sleep well on couches, but it is 10x easier to fall asleep on them
depends if you have the experience and confidence to get another comparable job. A lot of people are too timid about stuff like that and end up (sometimes rightly sometimes wrongly) feeling that their choice is between destitution and doing a shitty harmful job. Many would still take the leap, but many would be pained by that decision, especially if there was any ambiguity about how harmful the job was.
