ProPublica, Vox and Texas Tribune did a great in depth article on this last year, "The Extraordinary Danger of Being Pregnant and Uninsured in Texas". Most of what they found is applicable across the country, Texas just happens to be particularly horrific.

edit: "And Medicaid pays well for that."
> In Texas, as in other parts of the U.S., providers are paid only about half as much for Medicaid patients as for privately insured ones.
Not so in the US. It would be surprising if that alone didn't account for a significant number of adverse outcomes.
While there are many that don't have this kind of setup I don't know any country where care isn't free at the point of use. (Except for maybe your deductibles).
Also, Canada.
Yes so in the US. That's literally what the person you replied to just told you: For pregnant women, children, and poor people, it's all fully covered.
It's really only the middle class that has it hard (i.e. expensive).
