As an American citizen, what is your perspective on this?

In the US, hospitals are only legally required to stabilize you in the ER if your life is in immediate danger (under EMTALA). That does NOT mean treatment is free, nor does it cover long-term care like cancer chemo or burn rehabilitation. Once you're stable, they send you a massive bill that can easily bankrupt an average family—which is exactly why Americans rely so heavily on GoFundMe for medical expenses.

I saw even cops have to rely on GoFundMe to raise money for rehabilitation.

Medical bankruptcy is one of the major reasons why people's lives get ruined in U.S. and China.
