Example Input: Just because you don't pay income taxes doesn't mean you don't work. It may just mean you work your ass off to make life comfortable for people like the author of this article. And it doesn't mean you don't pay ANY taxes, just not income taxes. I get so tired of that "makers and takers" line of b.s.. It's not that simple. You want a sales tax? Fine, let's do it this way; exempt the first $500. of every purchase and tax every $ after that instead of the other way around. Does that sound fair to you?
Example Output:
No
