No, they do not. However I notice how you ignored the fact that when I was poor I received a "Return" on a tax I didn't pay. It was even a nice hefty one and that was long before I had children.Do all working poor have kids?
Does the EIC only apply to people below the poverty line?
No.
No one has showed me any math, that shows when you account for ALL taxes and fees at the federal, state, and local level that they get back more than they pay in, on average.
You are being deliberately obtuse if you miss that reference and zero in on just children...
