When I lived in New Orleans, there were always issues with flooding. The levee had been built (before I lived there) to protect the wealthy and historical parts of the city. The people who always got the worst of the flooding were the lower middle class and poor. :(

Either way, though, there is no excuse to abuse the volunteers who are trying to help. :(

You asked how people cannot help. Some people are not physically able to do what needs to be done. I fall into that category, but I find ways to help anyway, such as speaking to groups to generate fundraising or making reminder phone calls. I might not be able to lift a sand bag but I will hunt down and encourage those who can! I am finding more and more though that there are folks who just don't care about others which is truly sad. Thank you for being one of the ones who does care and steps up to help! *hugs*
