Personally, and I know a lot of other normal healthy people, don't want to have 10% of our income covering some guy who's paying nothing, eating cheeseburgers with a soda in the other hand and spending his insurance money on smoking instead.

Is this too much to ask that I don't need to be brought down for this poor behaviour?

The fact you're on reddit probably means you're not spending your time working your hardest, I'm not judging because everyone needs a little leisure time.

I guaranteed if you were working hard to succeed in life and paying thousands in taxes already you wouldn't be mocking the people who are, and you wouldn't want lazier people making decisions on how to use your money.
