And yet we let billionaires exist with their idiotic perchance for hoarding wealth and the rest of us suffer greatly from the wealth disparity. There are consequences for their actions and the majority should not suffer for the minority's idiotic habit.

Billionaires are wealthy because the companies they own stock in are successful. What are you going to do, make them sell the stock to pay someone else’s living?

It’s a rhetorical question by the way -- your position is not very defensible.

Insurance should be allowed to charge more if you smoke (though not that much more... dying early often results in less cost to the government/insurance company, not more).

But tax?

No.

That's a sociopathic way to think about someone who has made one mistake and developed a lifelong chemical dependence.
