Listen, if you pay less than the average amount of taxes, you're a leech. Period. Assuming our definition of leech is "takes more than they give." The entire system is built around this idea, so I'm not going to say its bad or good. Its theft, however, and I don't think anyone can disagree with that. Maybe you think theft is okay. I don't.
And driving on public roads because the government provides them doesn't make my argument for smaller government "just roads" why the heck would participating in a program that would make me better off? Even if its theft. The theft took place in the form of taxes. There's absolutely no reason not to take advantage of social programs while they're there, even if you abhorrently disagree with them, you'd have to be a self-hating moron to not use them
And this seems to fundamentally misunderstand allocation of resources... their tiny amount of taxes is nothing compared to what they get back. It makes no difference "where its going" in your mythical even distribution land, if they paid less in taxes than they received in food stamps / other benefits, we wouldn't be making the argument that taxes helped poor people... because they'd actually be hurting poor people, especially when you count overhead.
All that matters is net benefit in and net benefit out if we're talking efficiency, and not the morals of theft.
