The financials of leaving the workforce rarely make sense to me.

> There's tradeoffs in terms of career progression

There's X years of lost income, lost retirement savings, lost raises and bonuses ( depending on career ), lost promotions, lost acquisition of new skills which will keep the stay-home parent up to date with the modern workforce once they leave.

Teaching and nursing are still women dominated and famously supportive of women going back to work or starting work after staying home with the kids. For every other career path, good luck. How many people here would hire someone who'd be out of the workforce for 5, 10, 15 years without a second thought?
