There is nothing like several severe hurricanes and big floods to increase the number of hiring opportunities. I imagine there will be a lot of construction jobs out west too if the conflagrations there ever get rained out.
Natural disasters are good for some businesses but not for the overall economy. Personally I benefited because I was a short-term hire to adjust claims for an insurance adjusting company. Made $7,000 after expenses in just over five weeks during hurricane Harvey. Now that I understand their software, I can probably make $2,000+/week. when the next disaster hits.
But overall naturals disaster are an overall negative for the economy.
