You're being downvoted but I wish you weren't.
I've worked in healthcare, and pretty much my whole family does in all the professional roles you can think of.
I have mixed feelings about this article and others like it because the motivation to strip the system of everything until profit is left is a serious problem throughout US healthcare. However, it's not unique to private equity — private regional monopolies, or even privately owned clinics and hospitals, can have a similar effect. These articles then have a way of shifting the focus away from the underlying administrative practices that result in these problems, and toward private equity per se.
The regulation problem is real too, and I can give lots of examples. It's unlike a lot of other fields too in the scope and how ingrained it is in the system. EHRs are just one example: although well-intended, they were mandated with no "organic" roll-out, and pulled what was in-house staff and services and pushed it outside into large monopolies like EPIC (who are now the subject of an antitrust lawsuit IIRC). This happens over and over with all sorts of aspects of US healthcare.
I also have problems with the focus of these types of articles — for whatever reason, they often start with or are centered around this kind of wistful new physician (or very old physician near retirement) longing for the romanticized old days where physicians were in charge and ran everything. Should that be the case though? Do we really need MDs to do and approve of everything? Aren't there things that are done as well by PAs, DNPs, and other types of providers that don't even exist yet because of how calcified the healthcare system is? Can't patients do more at home without a middleperson — e.g., needing to approve of some medication that the person has taken for decades without incident and is really truly pretty harmless in the grand scheme of things?
The problem you described is very real. It's overregulated, in ways that incentivize large monopolies, either of clinic and hospital owners, or provider rent seeking guilds, infrastructure providers, etc.
I guess I feel like these types of articles point to one type of problem, but then tend to implicitly suggest the solution is to just roll back time to some earlier era, not recognizing that that earlier era had a smaller patient population, with less regulation, less monopoly where there was no need to scrutinize whether a certain type of degree is really necessary, where there weren't huge hidden overhead costs of all these monopolies permeating down to the patient.
Fixing US healthcare is going to require a bunch of things that collectively will cause pain for a lot of entrenched players: lots of antitrust lawsuits and laws, lots of deregulation aimed at giving patients more choice and self-care options, more public payer options, lots of eliminating or restructuring licensing requirements to create more types of providers, and so forth. They don't map on easily onto current US political party platforms either.
