> She made $45k year one, and a year later is the director of marketing at her company making over $100k/yr
If OP's daughter got a CS degree after two years she'd have made $0 and be $30k in the hole for state school tuition ($100k+ for private school). By my calculation she's $100k minus boot camp cost out of the hole.
According to Google the median income for a bachelor's degree is $100k, which includes experienced people in their working prime. So I think OP has a pretty good counterexample.
Also, not everyone wants to maximize their income. Comp sci now is what finance used to be, but not everyone has the moral framework or dedication to money where they can just Google highest paying jobs and choose the top one.
