Many years ago there was a free leaflet with people restoring paradise on the front and in the picture, a JCB!
I remember feeling cheated with that, because everyone knows that a JCB is a product of it's time and relies on numerous industries, processes, knowledge, manufacturing capabilities. To build one JCB, you would require literally hundreds of advanced industries and the educated people to run and work in the factories and facilities.
Hardly paradise. Back to the grind.
