Cleanliness or Overly-Cleanliness?

The latter. People are too overly-clean these days. I like to live in moldy damp conditions but today my landlord said it was "wrong". When did Western civilization go down this rotten path towards overly-cleanliness?

Nobody has so far died from using modern sanitation in the way that it's supposed to be used. American views on cleanliness on the other hand are very self detrimental. American parents don't let their kids play in the dirt or explore too far away from their house. As a result, their immune system never fully develops the way it should.
