<p>^ Here’s my take: any decision involving money inherently involves balancing opportunity cost. You could always do something else with the money. That something else could be: put it into savings for the kids as they grow up, use it for retirement, pay for medical school, go to Hawaii, or anything else. If you choose to spend more, you knowingly give up your opportunity to use that money for any of these other things. If your family examines the available options and decides that this trade-off is worthwhile, fine. But I do feel that families should examine the available options, because they may find that it is not a good deal even if they can make it happen.</p>
