How do poor people in the states give birth without money?

I’m Canadian. And I’m already sorry for asking an ignorant question.

I know you have to pay for hospital visits in the states. I know lower economic status can come with lower access to birth control and sex education. But then, how do they afford to give birth? Do people ever avoid hospital visits because they don’t feel like they can’t afford it?

Do hospitals put people on a payment plan? Is it possible to give birth and not pay if you don’t have the means? How does it work in the states?

How does it all work?

Again. Canadian. And sorry.
