It's not widely known in the upper/upper middle classes but healthcare is more or less free if you're poor in the US (even for major things like cancer treatment). It's really the middle class that has it the worst as they don't qualify for free health care.
Edit:
Some additional information to back up my assertion:
72.5 million people are covered by Medicaid: https://www.medicaid.gov/medicaid/eligibility/index.html
The vast majority of medical services are available for free to Medicaid members: https://www.medicaid.gov/medicaid/benefits/index.html
