I would say public education.

Central banks are inherently corrupt by design. Mainstream Media and the Healthcare system are corrupt but just following incentives. As perverse as those incentives may be.

Public education has become completely corrupted by politics and political ideology.

it's one big system, and i see it as one; additionally, each part plays off the other; furthermore, it's highly compartmentalized into a giant pyramid of control, where neither department is aware of what & how exactly the other is operating;

centralized media tells u to consume toxic industrial sludge thru every orifice, public education tells u to trust the media, sick-care system hands out some temporary relief that gets u hooked, and the banks are funding the entire operation;

i wud have included the enforcement cartel as well as the so-called justice system for a complete list; i think that the people in enforcement are totally owned, which is beyond corruption - that is total obedience, where the ability to think for oneself has been permanently destroyed;

Central banks are finally the final boss of corruption. Mainstream media gaslights you about it. Public education fails to explain it. And the healthcare system sends you the bill for noticing." To sum it up. It's not that the others aren’t corrupt - they absolutely are - it’s just that central banks do it with style: they quietly print your future into oblivion while telling you it's "for your own good." In this game of institutional Jenga, each block is rotten -but only one controls the wood, the glue, and the rulebook. Anyone else feeling this?

All of them.

"All of the above."

I have experience with the healthcare system, though not in the way you seem to be referring to—like with pharmaceutical companies and so on. My experience was related to surgical procedures, and both in private and public settings, the cost of medical supplies is absurdly high—not due to scarcity. Scarcity plays a role, yes—there are only a few players—but one of the main reasons for the high costs is the involvement of salespeople we often call “doctors.” They get their commission.

"whichever one I have the most experience with".

So - public education. Although the healthcare system runs a close second.

Central banks. More generally, money is fucked up. Everything else just follows fucked up incentives as a downstream effect.

Fix the money, fix the world.

Healthcare system here in New Zealand is almost free of corruption. It sometimes lacks funding when, as now, we have a right wing corporate sponsored government, but overall the public health system here provides care at a reasonable cost and quality.

We do have private medical providers but they are mostly only used by the wealthy.

I hear the US Health system is perhaps the most inefficient and inequitable health system in the world.

In some instances the free market does not provide as well as a well managed public service model.

And what about the options: -other -all of them

I would say Central banks, but very difficult to know which of these is more corrupt..
