If someone can't live comfortably on 5K a month then something is seriously wrong
You can easily spend over half that just on rent and utilities for something that isn't a sardine can and isn't an hour drive from your job. You can easily drop $1k/mo on health insurance, unless you like gambling or you think that "you employer pays for it" doesn't just mean "taken out of the labor budget on a different line". Used car loans are averaging over $500/mo now. Food easily that much too. Now think about trying to save on top of it...
I survive on 2500
Yes. You are among "the Poor". So am I. So are most Americans. It sucks.
But $5k/mo still isn't much either. It's also Poor. Double it and then maybe it would be a figure where you wouldn't have to worry about basic expenses going up. Probably more like triple it.
