One of these things is not like the others. If you don't spend the money on one of them, you can get a visit from government officials that might decide to take that "item" from you. You'd also be a worthless human to spend that money on the other 3 while not on the one.
I have profited richly from my children, but not in a monetary sense.
However much it has cost me monetarily, it has repaid itself ten times over in value to my very soul.
I (probably not obviously) meant the "too much" part, where kids fail to grow/launch when (optional) things are given to them too easily.
I didn't mean food, shelter, medical, education, lego, others-where-required-by-law.
