Exactly--I did a back-of-the napkin calculation at how much 20 years of self-employed healthcare premiums/college education for my four kids/4 years of daycare for 2 children comes out to, and it was three-quarters of a million dollars. Of course, most people have employer-based healthcare, so that number would be a lot less even though employees are carrying more of the burden of cost these days.
Would I accept a 50%+ increase in my tax rate to avoid paying $750k out of my own pocket? What a silly question.
