Why are threshing machines opposed by the poor in England?

Extensive scale enclosure forced the poor to leave their lands. They found their customary rights gradually disappearing. Deprived of their rights and driven off the land, they tramped in search of work. The coming of modern agriculture in England meant many different changes. The threshing machines helped the riche landowners to produce more with less investment as they started employing people during harvest only. Therefore, the poor in England opposed threshing machines as their income became unstable, their jobs insecure, and their livelihood precarious.
