I'm unemployed now but there was a brief time in my life when I was making quite a bit of money.
Enough to donate 75% to charity and still live comfortably, anyway.
Other than that time, I've lived beneath the poverty level often and grew up in social housing- worked 3 jobs all the way through highschool.. yada, yada, yada-- so, yeah.
Plenty of people live off of under 10k/year.
It's hard but it's possible. Just not comfortable.
You get used to not having any luxuries like un-processed foods,new clothing, cable or telephone. haha
