Australia has bulk-billed doctors and there's no shortage of them. I can book an appointment online for tomorrow, wait for 10 minutes in a waiting room and see a GP for free. I can even choose which GP I want to see. And I'll likely get anything they prescribe me for free as well. Medicare refunds so much money I sometimes feel guilty because I know I can afford it.
My partner has a chronic health condition that resulted in her large intestine being removed and she requires thousands of dollars worth of medication a month, likely for the rest of her life. We've never paid for surgery or medication beyond admin or prescription fees.
I want this for everyone and I pay my taxes gladly. I would pay more for an even better system. You don't have shit if you don't have your health.
