Friedrich List

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.

Industry entirely left to itself, would soon fall to ruin, and a nation letting everything alone would commit suicide.
