The concept is ridiculous. Why do people assume that the government, for all its faults (and they are legion) can just swap money from place to place? It is almost childish in its naïveté. It's not a household budget!
Certainly the government must get its house in order; certainly it must find money to restore people's lives and livelihoods, but not, even if it were possible, at the expense of others.
And, while I have the utmost sympathy for those in flooded areas, and agree that their needs are great, few of them thank goodness, are dying from water borne diseases, or are starving, or will die before that are in their forties etc. etc. there are emergency services and NGOs ready and able to help; there are medical services available. It is impossible to equate what, for us, is a disaster, with the many, many worse situations around the world.
