Answer:

The spinning jenny is a multi-spindle spinning frame, and was one of the key developments in the industrialization of textile manufacturing during the early Industrial Revolution. It was invented in 1764 or 1765 by James Hargreaves in Stanhill, Oswaldtwistle, Lancashire in England.

The machine used eight spindles onto which the thread was spun, so by turning a single wheel, the operator could now spin eight threads at once. The early spinning jenny also produced a weaker thread than could be produced by hand so there was a decrease in quality until improvements were made to the machines and a dependable power source became available.

The spinning jenny allowed more threads and yarns to be produced by fewer spinners. The early spinning jenny also produced a weaker thread than could be produced by hand so there was a decrease in quality until improvements were made to the machines and a dependable power source became available. It sparked a movement that would change the lives of people worldwide. The economy had been stagnating for centuries. Eighty percent of the world's population was working in the countryside; many were malnourished, with an average life expectancy of 28 years.

But since I feel that you are men of genuine goodwill and your criticisms are sincerely set forth, I would like to answer your statement in what I hope will be patient and reasonable terms.
