In Brazil, health is a constitutional right. Brazil has free, universal, and unlimited healthcare. Public hospitals in large cities are on the same level as private hospitals, and both are excellent.
If you want faster non-emergency care from a private hospital, you can purchase health insurance. Doctors don’t need approval from the insurance company to perform treatments or prescribe drugs. If the drug or treatment is listed on the insurance’s website as covered, it’ll be covered if prescribed by a doctor.
Since public hospitals offer almost all treatments and drugs for free, private hospitals and insurance companies are forced to offer lower prices and support more treatments to compete.
Non-essential surgeries like LASIK are very rarely supported by health insurance in the US, but are covered by most in Brazil.
Despite all of that, the average Brazilian only pays 27.5% in income taxes vs 37% in the US. The US government’s health expenditure per capita is $12k, versus $1.2k in Brazil.
It isn’t perfect, but people in Brazil don’t go bankrupt because of health problems. They don’t have to fight the insurance companies for coverage, they don’t die untreated of cancer, they aren’t afraid of calling an ambulance, and they pay less taxes for it.
