I know of someone who goes to food and to save money. Not because they need it.
Assuming you mean food banks, most of these are based on referrals so this is unlikely.
Many well paying jobs come with free or subsidised work canteens, free business lunches, expense accounts etc.
But these are for all employees so the lowest paid workers have access to these too.
I’m pretty well off. I rarely have free food and if I do, it has nothing to do with my earnings.
OP is not wrong though, there are many, many ways that people are trapped in poverty because of how the world works. Key meters, bank charges, higher credit costs, ATMs which charge being mainly in poor areas, food deserts meaning they rely on smaller, more expensive stores etc. These things need to be legislated against if we want to help people out of poverty.
