From both the context and the picture it's clear she's not actually, you know, retiring. The amount in someone's retirement account is meaningless unless you know their age and their income. Yeah, $10k isn't a lot if you're in your 60s and living a lifestyle that costs 6+ figures a year; it's a lot if you're making $30k a year and are in your 20s, and quite understandable if in your 30s at that income level. Three jobs are quoted because yeah, they probably are part time (and just saying "works 60 hours a week" or whatever doesn't carry the same punch), but -they may not be able to get a full time job-. Or else...you know, they might have healthcare.
The emergency room has ludicrously high costs, and none of his medical history. You're literally saying "don't expect to be able to see your primary care provider, go to the emergency room instead" -because of existing debt-.
You're making a lot of assumptions...all of which miss the point. Why is life shattering medical debt a common thing we tolerate in this country, given every other Western country has managed to make it a rarity? But, to your assumptions - maybe and she gave birth prematurely and ended up being seen by a hospital who were out of network and her insurance didn't cover it. Or even went to an in-network hospital, but was seen by doctors who were out of network, as frequently can happen, especially in emergencies when you can't personally vet the doctor is in network for you before you see them. Certainly, something unexpected happened (maybe even the pregnancy itself! Something to look forward to with the Supreme Court set to overturn Roe v Wade), and insurance wasn't there. Why is that acceptable in this country?
