You can't have the good without the bad. Flooding exposes towns that are not brought up yet, that don't have the investment in infrastructures. Small towns are small for a reason so small is small. It's like running a Marathon holding your breath your not going to make it to the finish line. So you don't expect success there so you get the bad that just does not keep up!
Also many rich people tend to build close to the river that will eventually flood. Rich people live at better places as you hardly see the police in a rich neighborhood as the slums referring to educated people live better lives and so better places. But your education is only worth the paper it's printed on not questing your education points to Smart as not really being smart. But this is a small number of people that build too close to harm vs town being flooded.
The point of all this if there is a flood in that place don't live in that place you will just be setting yourself up for failure!
