The only thing easier to subvert and influence with bad habits and instruction than a modern man is a trainable pig.
Then again you gotta work at training a pig. All you’ve got to do with a modern man is just drop him in the center of his supposed “culture” and most of them will reflexively absorb by osmosis every low social custom they come can possibly come into contact with.
Modern man is hardly known for his strength of mind and soul. He is, however, very well known for how easy he is to corrupt, pervert, and manipulate.
