Perhaps, but very pertinent to the topic at hand. Many people choose to have a boatload of kids when even a fool can see that it is a highly questionable move financially -- my parents being examples of such fools, as it happens. If you cannot afford the lifestyle, having kids because you want them is no different than buying a plasma TV because you want one. Except in the case of having kids, the parents' financial foolishness may be visited on them in various ways.
I have no problem with people having huge families, but it is a selfish financial choice based on personal desire just like every other such decision. We make our choices, and live with the consequences, and having children is unambiguously a voluntary personal choice. If one chooses to have children, one should not complain to anyone else that they are expensive to maintain -- anyone should have known that going in.
If your parents had been "wiser" which one of your brothers or sisters would you have prefered they passed on? What if it was you?
People who believe children are simply an indulgence and expense and not an investment should be required to live in a country where the birth rate has collapsed. Such a country is destined to collpase and die. Japan and much of Western Europe are in the early stages of that terminal state now.
