For my kids, health insurance premium would have been almost $2k
per month. In a typical year we spend about $1,200
total on medical stuff just paying out of pocket. Also keep in mind that premiums are not all you pay - there's also deductible and co-pays on top of that!
It's not hard to math that up and see how insane doing the health insurance would be. Yes there's the catastrophic risk of a bad accident or ER visit or something, and that's worth some cost, but even saving half the premiums in a money market account not only provides a good cushion for that, but if we don't use the money we actually get to keep it!
