OK yeah the medication is expensive, the pharmacies are rigged. Farmacias Ahumada, Farmacias Cruz Verde, and Salcobrand are three divisions of the same single...trust, basically. The Chilean pharmacy monopoly. Enforced with eg intermarriage. However, now there's lots more pharmacies, it's opening up. And I am personally boycotting Cruz Verde in almost all circumstances because I saw a shill of theirs (a real life shill, not on a forum, in a brick-and-mortar retailer) shilling for Cruz Verde[1] at a pharmacy that actually competed with them. There's some.

But I don't know, did you try the municipal pharmacy in Recoleta? Way cheaper.

[1] Note for admins: this is not the same as calling someone a shill on the forum, I went and gave my account and signed an affidavit in the complaints and suggestions book, with the help of the guard who also witnessed the shill, and backed by a third witness who conversed with the shill like I did. I told them by all means use this in court, I'll vouch on the witness stand, and I'm doing this with the same moral authority and motivation of being a hero according to Roman Law, in a very similar set of conditions that led to my actions and consequent recognition as a hero by the victims in the spur of the moment, ten years ago.

Looking at this it’s mind boggling how much the US is being overcharged vs all other countries. How are Americans putting up with paying 400%-900% more than any other country?

It's not "putting up with". What are they going to do otherwise, not take insulin?

Demand action from their representatives. Works in a lot of other areas but not in health care. I guess the lobbies are too strong.

Those so-called "representatives" created the problem in the first place by restricting the supply with drug patents, FDA regulations, import restrictions, and limitations on the number of new doctors and medical facilities, and now you want to "demand action" from them on behalf of patients? Good luck. They're representing someone all right, but it's their donors, not their official constituency.

That, BTW, is a consequence of the system responsible for selecting and influencing those in power and not any particular individual, so voting in someone new won't change anything. And that goes for much more than just health care.
