Danh ngôn của Friedrich List (Sứ mệnh: 5)

But the general welfare must restrict and regulate the exertions of the individuals, as the individuals must derive a supply of their strength from social power.
It is bad policy to regulate everything... where things may better regulate themselves and can be better promoted by private exertions; but it is no less bad policy to let those things alone which can only be promoted by interfering social power.
