Bear in mind Portugal has healthcare and legalised all drugs.
It's also my understanding that healthcare was a big part of what convinced people in the UK to vote for Brexit.
Now this should not be the end of the story. I understand there are folks who need medical treatment that can not afford it. There should always be a mechanism to make sure folks get the necessary help. I would hope the church or some other private entity would step up -- and often do. If not, then the final catch is the government.
The government taking over the whole health insurance industry is a naive solution that will result in crappy coverage for everyone. I don't claim to have a complete solution -- it is a difficult problem. I don't like extremes in either direction : completely privatized and completely government run are both bad solutions.
This is demonstrably false when you consider the quality of coverage in places like France and Denmark.
I find the fairness argument understandable from a distance, but it falls apart when you look closer and realize the amount of overhead involved in managing such a system where we make sure everyone pays according to their risk profile, which itself, would be dependent on numerous subjective measures not to mention the potential for intentional or unintentional inaccurate reporting. As an example, our tax dollars go to pay for infrastructure whether we're driving on the roads and bridges they pay for or not, and we don't pay more or get refunds if we use more or less roads. Would it be fairer to only charge you for roads you use? Absolutely, but it'd also be a ton of overhead to administer.
