Is that before or after taking out earned income credits and all of the other "deductions" that people use to avoid paying their fair share?

I personally know of at least a dozen people (my ex for one) that get between 4ooo and 5000 dollars back annually but pay nothing in.

Makes sence don't it I have 2 kids I'm a student my wife is a student we both work and our returns never look that good. My ex has only 1 minor left at home collects SSI and still gets 5000 back every year if this type of nonsence were discontinued along with a few other BS programs I think 10% would suffice.
Incidently other common deductions would be eliminated these include: mortgage, student loans, kids, property taxes(which apparently in some states is tax deductible)(maybe even at the fed level, don't know the misses handles our returns) and I imagine there are others but they elude me right now.
