I thought the discussion here was about cataract surgery.
Australia has "free if you're poor and can wait" o/wise relatively cheap depending on your private health insurance.

Seems misleading for that site to say it’s free. There’s small fees which you end up paying that Medicare doesn’t cover. And afaik you require a referral for public hospital which is not covered.
I'd wager that small referral fees in Australia amount to considerably less than surgery costs in countries with no socialised health care systems.
You’re kidding yourself if you think people on HN are contributing anything to better society.
