Lao Tse says about number 3:
Not exalting the gifted prevents quarrelling.
Not collecting treasures prevents stealing.
Not seeing desirable things prevents confusion of the heart.
The wise therefore rule by emptying hearts and stuffing bellies, by weakening ambitions and strengthening bones.
If people lack knowledge and desire, then intellectuals will not try to interfere.
If nothing is done, then all will be well
