In peace time, the US government used to spend very little on defense, about one percent of GDP. But that changed after World War II when the United States found itself in a global contest against Communism.

Consult with a licensed plumber if you intend to install a clawfoot tub on the second floor of your home! Insulate the pipes well during the installation process, if your supply and drain pipes will run through an unheated (or under-heated) space in your home. Consider your water heater! Clawfoot tubs can hold anywhere between 40-60 gallons of water. That means one good soak could completely drain your 40-gallon water heater. That may not be a consideration for you, but the rest of your busy household might be inconvenienced when someone is using the tub.
