FAANG employee health insurance? Something like 1% of American workers get that, if even that many. Then throw in my oil company friends here in Houston and a few other industries which give premium benefits and you still have a tiny subset of the American workforce getting exceptionally strong benefits. Not at all indicative of the experience of most Americans.
The universities I worked for (both public and private) provided the same level of PPO insurance, as did a random fitness startup, a clinical diagnostics company, and a construction company. I invite you to reread the part where I said “several employers [plural] ranging from university to FAANG”.
