$4 would get you an egg sandwich, a coffee and a pack a smokes in ‘83.

In the US, yes.

I'm guessing they're from somewhere else where cost of living may be different.

If it's only food, it's definitely possible. Rice and beans is probably less than 50 cents a day. Then you can get some cheap chicken thighs for like 1.50 a pound. Then get some carrots, broccoli, and onions. It should cover the majority of your nutrient needs for $4 dollars a day.

CPM/RPM isn't per day, it's pay per 1,000 views.

it is possible here, but it kind like kills the future, loosing friends. very slow pace of living, like in 10 years if something improves, it is wise if the body still healthy haha..
