I'm assuming from your response that you've never read "The Grapes of Wrath". (Another failure of our public education system I guess).
You might be surprised what you can learn from books, though it does take a little more concentrated effort than posting on a website.
GofW describes a natural disaster, the transformation of large parts of the south central US into a dust bowl, and the resulting migration of poor farmers to California looking for work. Probably the largest migration of Americans in US history, until Katrina and Rita.
Then as now, there were people around who didn't think these people were owed anything and they were run out of towns and exploited for their desperate need to make a dollar. There are some parallels.
Just thought you could use a little historical perspective my friend. People live in all kinds of potential natural disaster zones. I don't know where you live but I hope you're practicing what you're preaching and you're paid up on your insurance for earthquake, fire, theft, volcanos, burglars, meteor showers, and wolverines.
Say, you're not an insurance man are ya?
