Ever heard the phrase "has more money than sense"?
Do you have kids? Do you know how expensive it is to raise them? The preschool costs around $3k/mo at least. Compared to that $300/mo is pretty minor and the convenience it offers is totally worth it.
You're out of your mind if you think most people with children are paying $3k a month for child care. $3k a month is the entire income for a minimum wage couple with a child isn't it? I don't think your experience is typical.
