Alcohol is not

[Xinfu]

Are my sentences good English?

-Alcohol is not conducive to good behaviours.
-Sleep does not lead to wealth/is not wealth inducing. (in reply to 'why are you such a failure?'/'why are you so poor?'
-The broadness of character does not ensure visual enjoyment. (in reply to 'why is your wife so ugly?'

All are good English.

You didn't provide the 'in reply' aid for the first one, but I wouldn't pluralize 'behavior'.
