Since mimi's not weighing in here, we'll just have to give her the benefit of the doubt that the rest is in state taxes of some sort.  I'm not very good at percentages which is why I just looked for the hard numbers per year.  How much is social security and medicare, do you know?  Don't go to any more work to answer, though.  It's starting to feel like H & R block in here! :-)

Seriously, though, I think this whole discussion has illustrated one of the political problems that the Republicans have been capitalizing on.  A lot of the lower income folks here aren't making it financially.  If you can afford an IRA and medical savings and a mortgage, you can end up paying much lower taxes.

But if you're someone living and working in an expensive inner-city, someone who's struggling to pay their bills, that $200 a month or so in taxes really hurts.  All of your living expenses are sky high, you pay sales tax and taxes on your car, gas, and some utilities, you add those taxes up and wonder why the hell you're paying so much when Enron didn't pay any federal taxes some years.  

This is hard evidence to these folks that the system stinks.  It's why they vote "against their interests" for the "low-tax" Republicans.  We keep wondering about this working class "insanity" without addressing the underlying issues the Republicans are speaking to with their rhetoric.

Maybe we can eventually make language a complete impediment to understanding. -Hobbes
