Why would it be different in other branch?
Lack of choice; the government has captured the "market", and "consumers" can't choose to go anywhere else. Compare to the service (and especially customer service) offered by your cable/internet provider where you have not choice. The cable companies vie for literally worst customer service of all businesses year in and year out.
And we know that the government is doing an awful job in regulation of healthcare. I've got kind of a front-row seat to this and see things that most might not, since my wife's whole career has been in healthcare finance, and in particular around how Medicare reimburses hospitals for services.
She's currently working with one client hospital for whom their Medicare cost report still hasn't been resolved for some years back even before 2010. How can a business operate efficiently when they don't know what their expenses are going to be - not just in the future, but even historically, more than 10 years into the past?
Worse, the way the government forces hospitals to report this stuff is extremely specific, and optimized for how Medicare wants to run things - which is why Medicare can claim to spend less on administration: they just force hospitals to do all the administration for them. And hospitals can't say "no", with Medicare (together with Medicaid, which generally rides on Medicare's regulatory coattails) comprising a plurality of the market, if not an outright majority. The result of this is that hospitals have a choice of either running two separate accounting systems (one for what Medicare demands, and another to do rational cost accounting), or more likely, to just do the one for Medicare and muddle along as best they can. And that's a major reason why hospitals can't operate more efficiently.
And my wife's currently involved in a battle with them over some detailed rules they posted early in the summer. She's been working all summer for her client hospitals based on what the government posted on their website. Last week they changed the rules posted (you can even see the "last changed" date). But the change was in a way that contradicts their previous statements, and invalidates much of what she did all summer - and worse, they're lying about it, not admitting to what the previous version of the page said. Unfortunately the wayback machine didn't track that site, and while she's got her own records quoting the page, the gov't won't acknowledge it.
So there's a clear explanation for why it can get bad, and tons of evidence that it really is bad.
In addition to this, it's worth pointing out that the idea that Medicare is the solution to all of our problems because of the cost savings of administration is way over-stated.
There's a pretty great breakdown of where per capita costs go in the US vs comparable OECD countries -> https://www.healthsystemtracker.org/brief/what-drives-health...
Administrative costs make up a tiny percentage of the overall cost differential. You could basically zero it out, and it would still hardly make a dent on the overall cost difference.
The US Military runs the VA, and that's also been a noteworthy embarrassment -> https://www.cnbc.com/2018/05/28/va-veterans-affairs-history-...
Outside of raw warfare, the military runs almost entirely on cost-plus, which results in over-spending of contract money for boondoggles that just entrench the military industrial complex.
Outside of the US military, you have systematic inefficiencies like this across most major agencies.
NASA's planned SLS moon mission is a bit of a disaster — way over budget and way behind schedule. Because the boosters aren't reusable, each launch is expected to cost $1B (with a B) dollars — EACH launch! Meanwhile SpaceX's target cost-per-launch is $50M.
In healthcare, Medicare has actually been running a fairly interesting A/B test. When you turn 65, you have the option to enroll either in "Original Medicare", which is what we usually think of when we talk about "single payer healthcare in America", or you can enroll in Medicare Advantage (aka Medicare "Part C"), where the premiums that would go to the CMS instead go to private insurers like Humana, United, Oscar Health, Clover, etc. These plans replace Original Medicare, also cover Part D prescription drug benefits, and often include supplemental benefits that Original Medicare doesn't already cover. The outcomes are fairly interesting:
- 36% of Medicare beneficiaries are on private Medicare Advantage plans instead of the public "Original Medicare". Because everyone is entitled to "Original Medicare", this is purely voluntary. This number has been growing so rapidly, that we expect by 2025, more seniors to be on a private plan than the public one. There's also great variance by State. In Florida, Pennsylvania, Wisconsin, Michigan, Minnesota, Oregon, Alabama, Hawaii, and Connecticut — over 40% of beneficiaries are on Medicare Advantage. By 2022, we expect more seniors in those States to be on a private plan than a public one. https://www.kff.org/medicare/issue-brief/a-dozen-facts-about...
- For most beneficiaries, Medicare Advantage costs about 39% less than Original Medicare. https://healthpayerintelligence.com/news/medicare-advantage-...
- Medicare Advantage plans are, on average, of higher quality than the public "Original Medicare" https://healthpayerintelligence.com/news/medicare-advantage-...
- In Urban areas, Medicare Advantage costs less per capita to administer than Medicare — and that's not including the extra Medicare Part D insurance that you would have to buy if you're on the Original Medicare plan. https://www.commonwealthfund.org/publications/issue-briefs/2... From this same research, public "Original Medicare" is still cheaper in rural areas, but not by a whole lot.
So yeah, while the governments of a lot of countries are fairly robust and efficient, I think that suspicion is warranted, especially in the US.
