I looked up the etymology. The word has been around for centuries. In classical economics the word refers to physical effort.

The ngram of "labour" v. "labor" is interesting. The short spelling became more popular after the rise of the Labour Party.

Marx was seeking to start a revolution; so he sought to create conflicts between the "proletariat" that labored for a living and the bourgeoisie that owned things.

Is labour really in conflict with ownership? The kid owns a strimmer and offering a service.

I hope that he bought a better strimmer. The electrical trimmers have improved greatly in the last few years. The gas powered ones are being outlawed.
