The United States often suffer from the ravages of hurricanes (tornadoes). Why do they continue to build plywo

Question

"plywood" houses on the coast? They must build fortified reinforced concrete homes or perhaps underground refuge.
How strange-US so rich ...

Answer 1

If built right, even plywood clad homes can withstand category 5 hurricanes. But the reasons why such homes "blow apart" in hurricanes are 1) inadequate building code standards for high risk areas, and 2) contractors trying to be cheap. The VAB at NASA's Kennedy Space Center near Miami (see wiki) is neither "reinforced concrete" nor "underground" (it's the largest "empty box" building in the world) has withstood all the hurricanes to hit Florida so far. It's just an engineering matter.

Answer 2

'plywood' homes? They build them because they are inexpensive, to build concrete or underground homes would cost three times as much per square foot. Most of these areas are poorer areas of the nation, generalizing by calling the US rich is inaccurate and unfair.

Answer 3

Cost is the answer, buidling a fortefied concrete structure costs very serious money.
