Why do Americans keep building wood houses?

It's something I've been wondering for a while, and I thought I could get a bit of insight on the subject.

It puzzles me why americans build houses with wood as its main structural material. Ok, I get it: it's cheap and fast to build a wooden house, but I'm sick of watching news about tornadoes destroying whole neighbourhoods... and then rebuilding those same houses with the absolutely not tornado-proof building material that is wood.

Also, danger of fire, moisture, structural fail is more prone to happen within a wood house.

Wouldn't concrete or bricks be a more suitable material for housing?

Any tips?
