My quick Google search reveals one source which claims that this comes from McCulloch's 1826_An Essay on the Circumstances which Determine the Rate of Wages and the Condition of the Labouring Classes_. I cannot locate the exact page reference, since I only have the revised edition. 

An update:

The McCulloch quote is in pages 16-17 in _A Treatise on the Circumstances which Determine the Rate of Wages and the Condition of the Labouring Classes_, second edition, corrected and improved, 1854.

Yours,
