Labour was the first price, the original purchase-money that was paid for all things. It was not by gold or by silver, but by labour, that all wealth of the world was originally purchased -Adam Smith
The first day of the fifth month, May 1, is celebrated as International Labour Day. It is, at its heart, a celebration of man’s ability to produce, his ability to chose, his ability to think. Man is the only animal capable of barter. He can exchange his time, his labour, for the fruit of another’s.
