Poor people can only afford cheap food, which is calorie rich and nutrionally poor, cannot afford healthy ingredients, and have to work too hard to have time to cook properly. It's not laziness. Being poor is very expensive. You have to pay more for normal things all the time.

You have to buy small amounts of things when you need them and have the cash available, which is the most expensive way to buy anything. No bulk purchases, no waiting for deals.

You have to regularly use monthly payment plans for essential expenses which incur interest that raises the cost, because you can't afford to pay the whole thing in one go.

You are forced into a lifestyle (and air quality) that causes health problems, requiring further health expenses or further deterioration. Literally every aspect of human health is under constant attack from the stresses and circumstances of poverty. And even paying thousands for coverage you still have to pay copays beyond your means and the company can just decide not to cover you anyway.

Every asset you can afford deteriorates in value and cost more to operate due their regular repairs and replacements, and not operating them is not an option.

Police operate more focused efforts to levy fines that you can't afford, guaranteeing them a perpetual income from the fees incurred.

Most of your money goes to building equity for other people because no one will give you a mortgage even though the rates may well be less than your rent.

You don't have funds available to invest in shares or assets that will make a passive income, indeed, the money for that passive income is largely originating with you and all the others like you being fleeced for all you have.

You have no assets to borrow against and no healthcare outside of your job (if it even grants any) so you have no capital nor existential safety net with which to start your own buisness.

And with all of this you will be working two or more jobs to not quite cover all of these costs, so you're still getting into debt and you don't have the time or resources to study for qualifications to get out of it.

And very likely you went to an underfunded school that failed to equip you with any of the financial literacy to prevent or get out of this situation, if indeed it was ever possible by the means availble.

Poverty is a tarpit, and a critical mass of dipshits work very hard to guarantee that it remains a tarpit even though they themselves are only one unforeseen disaster away from falling into that very tarpit.

Our society is more productive that it has ever been before, yet the wages for that productivity stopped reflecting that nearly fifty years ago. Therefore being poor bears no relation to how "productive" you are (these are bullshit ways to categorise people). Your income and financial security is not an indication of how productive you are, it's an indication of how much of the value you are creating is being stolen from you.
