Hurrah for the law of Supply and Demand,
That regulates everything in the land,
The rate of wages, the price of stocks,
And the size of the Vanderbilt pile of "rocks."

It keeps in subjection the dull Labor hordes,
It fills up the chests of our great money lords,
And when for just reasons they're brought to a stand,
They've only to answer, "Supply and Demand."
