But if women earn less, aren’t they already in lower tax brackets?
Yep but, the concept can not be based on gender alone.
If a woman earning $35K with a family of 2 is given a tax break that a man earning $35K with a family of 2 and both are single parents and the woman gets that tax break just because of her gender; it’s constitutionally illegal.
Very intuitive of you Paleo.
Since I am a single "male" (gasp) my total tax burden only exceeds 50%, however hey! others need a break too!
