As a sibling comment points out, health insurance and child care consume quite a bit of a wage in the US (our employer portion is $20k/year alone for a family of four; childcare is easily $1k/per child/per month for 2 days a week of care). My wife is giving birth tomorrow to our second child, and we're prepared for a bill anywhere between $5k-10k all-in, even with a quality insurance plan at my company.
