>>you have to fund the super expensive good for nothing public one anyway.
My father had battled cancer in Polish oncology hospitals and has received nothing but top tier treatment wherever he went. What's more, NFZ completely funded the treatment with then-experimental Glivec for him, which was billed at around 200k zł/year(in US, a year of Glivec treatment is around $100k). In the course of 8 years of cancer he had to stop working due to the ilness, and yet was still fully covered and received the same treatment as always.
So no, it's not "expensive but good for nothing". It's not expensive compared to private treatment, and it's extremely good if you have a major ilness. I agree that routine treatment and appointments are in shambles, but that's universally true pretty much everywhere in Europe right now, the waiting times in countries with public healthcare systems have inflated into infinity due to a combination of factors. But even in Poland, I wouldn't dare to not pay into the system - it's too good not to pay for it(and I do, in fact, pay for it).
