> approx 50% of my income goes to taxes

I sincerely doubt that. You get the marriage subsidy, the child subsidy. If you're paying a mortgage, you get that subsidy. You get a subsidy for your retirement plan. You're already paying substantially less than a similar income single, childless renter.

I know you're including taxes that the companies pay, whose products and services you buy, but there's no way to estimate what they'd charge you in the absence of taxes, so that's pure speculation.
