Starting CPAs in the big accounting firms start at about 60k in the smaller places can be 50k. Takes a pretty long time to make 100k and by then you need 200k once your paying tuition and health insurance... Not everyone can become a lawyer or Dr and even those that do are not guaranteed an income above that. Maybe a grad from a top law school can get that starting. One of the biggest expenses families face nowadays is healthcare and it keeps getting more expensive and covers less.
Based on my current income I can't even see the day my wife can cut her hours or stop working, growing up 2 income families was not necessary.
