Democracy in America, Volume 2 by Alexis de Tocqueville

I have shown that democracy is favorable to the growth of manufactures, and that it increases without limit the numbers of the manufacturing classes: we shall now see by what side road manufacturers may possibly in their turn bring men back to aristocracy. It is acknowledged that when a workman is engaged every day upon the same detail, the whole commodity is produced with greater ease, promptitude, and economy. It is likewise acknowledged that the cost of the production of manufactured goods is diminished by the extent of the establishment in which they are made, and by the amount of capital employed or of credit. These truths had long been imperfectly discerned, but in our time they have been demonstrated. They have been already applied to many very important kinds of manufactures, and the humblest will gradually be governed by them.

I know of nothing in politics which deserves to fix the attention of the legislator more closely than these two new axioms of the science of manufactures.
