The American elite do (and have always) taken steps to insulate themselves from the rest of the system, including medically. There are "boutique doctors", "family physicians" and the like.

It's actually not that hard to find them, they just don't take insurance. The prices are not that high if you are not going to be back on a recurring basis.

You're still in the blast radius if your loved ones or friends suffer unnecessarily due to the healthcare industry. It's so pervasive that it's not to hard to imagine a scenario where this guy was disgruntled by simply observing the brazen profiteering taking place at the expense of human life. Many have shrugged it off as status quo capitalist behavior, but if you choose to go down the rabbit hole you'd find it very easy to locate people who have been on the losing side of the healthcare industry
