The gain is from married filing jointly while one partner is not working. At $100k it roughly halves the income tax you pay.

Or where one partner earns significantly more, like $150k vs $50k - joint filing still puts you in a lower tax bracket.

If im taking care of a partner, i should be able to deduct expenses up to my total income like corporations can. halving the tax is still not enough to move the needle for people to get married due to better taxes.

This results in those in higher income tax brackets receiving far more money which is deeply inequitable.

Having single men pay for other men's children, incentivising single motherhood seems inequitable, no?

Lions are smarter than us.

Ugh. What a horrible thing to say.
