No it's not just FAANG. Just FAANG literally imply only Facebook Apple Amazon Netflix and Google offer healthcare. So I need to find only one more company that does offer healtcare to disprove you. And I'll name Intel where I worked. But likely all companies with 50+ employees offer you healthcare. Also healthcare is not so expensive given the salary you receive. The problem of private healthcare is a serious problem related to people in the USA earning 0-50.000$ a year. After that private healthcare paid in advance costs few hundred dollars per month and you can definitely afford it with a software engineer salary.
