So someone who has lived a clean life free from cigs and drugs but can’t afford healthcare should just die if they get sick? Should they be strapped with a lifetime of medical debt?

That's a strawman. Most people are overweight and don't exercise.

What about people who pay for insurance, but smoke a pack a day? You do realize that those costs are averaged out so that you are paying the extra cost of care through increases in your premiums.

You have to tell the insurance company if you smoke and you will pay more. If somebody lies about that I can't stop people breaking the law.

Why wouldn’t you want your fellow countrymen to be healthy and productive in society?

They can be healthy, 99% of the time it can be achieved with eating healthy and exercise.

What does paying taxes have to do with healthcare?

If there's universal healthcare they will need trillions in tax dollars. Do you think it comes out of thin air?

What about people who work 3 part time jobs, thus are not eligible for benefits such as insurance? Do those people not pay taxes?

Tax doesn't pay for insurance. They can get private insurance.

Who deserves healthcare in your opinion?

Orphan children.
