the Weasleys being poor
I never understand this and feel almost as if it's a plot hole, because, logically, how? Really, how? If you can do magic, no, that won't solve life, but it makes money much less important. There are spells where you can multiply food, so buy enough for one person and keep multiplying it until there's enough for the whole family (and they seem to farm some of their own food anyway). Your house needs repaired? Boom, magic, done. Clothes need repaired? Magic. Need new clothes? Just buy fabric and magic up your own clothing. With all the magic cures, seems less need to go to doctors, so not as many high medical bills. Between Apparition and Floo Powder, travel's not terribly expensive. I just don't get it.
