Well people make money buying diapers and shipping them, and delivering them to stores. So we buy them and the companies make more diapers because we keep buying them so they make their money. Same as stores when we go to them and buy them.
Now that the economy is bad, I can imagine people have cut back wearing so they buy them less so the companies make less money because they don't need to make as much diapers but thank god for people who do need them so they are still in business. I can also imagine people have cut back on cloth too because they want to keep their laundry down and that means it keeps down their electric bill and water and they use less laundry detergent.
