When I was a kid I heard a song from a music teacher about labor. This is all I remember of it. Does anyone know it and if or when it is recorded?

Give me a price for my hands
My two hands are mighty hands
They're how much milk at my door
How many pounds will my children weigh
Give me a price for my hands
But remember this before you do
That my two hands are mine to sell
They made your factories
They can stop them too
