what make people mad isn't the compensation, but the inconsistency.
if government has policies that pay out relief for disaster then it is right, if not and only for this event then it is pathetic.
giving $15k right now seem like putting a bandage over a bleeding heart, covering their embarrassment for incompetency by waving the dollar signs, and shutting up victim families. aka. you got money didn't you, what are you complaining about. and bolstering their supporters that government had already did their part by paying and decreasing empathy toward victims. what about apology? investigation? waving money BEFORE doing all of that is such a slap to the faces of the victims and society.
