Now I somewhat agree, yes, the main objective is to make the most money, HOWEVER reducing manufacturing costs is only one aspect to this. Marketing is the other. On a whole, most people who need diapers aren't necessarily proud of it, so the cloth covers help them 'hide' it much better. The cloth apparently also breathes better. So it's not just a big gimmick.... whatever will make the most money in the end will be what is on the market - whether that means reducing manufacturing costs or improving marketing strategies.
