One doesn't have to be a Luddite to appreciate what they did - risk death trying to prevent what they perceived as an oncoming tragedy.
The machinery wasn't labor-saving as much as "labor payroll saving."
The Luddites were not, as not only popularizers of theories of technology but also capitalist apologists for unregulated innovation claim, universally technophobes. The Luddites were artisans -- primarily skilled workers in the textile industries in Nottinghamshire, Derbyshire, Leicestershire, Cheshire, the West Riding of Yorkshire, Lancashire and Flintshire in the years between March 1811 and April 1817 -- who when faced with the use of machines (operated by less-skilled labor, typically apprentices, unapprenticed workers, and women) to drive down their wages and to produce inferior goods (thereby damaging their trades' reputations), turned to wrecking the offensive machines and terrorizing the offending owners in order to preserve their wages, their jobs, and their trades. Machines were not the only, or even the major, threat to the textile workers of the Midlands and North. The Prince Regent's Orders in Council, barring trade with Napoleonic France and nations friendly to France, cut off foreign markets for the British textile industry. Even more importantly, famine and high food prices required more of each laborer's shrinking wages. Machines and the use of machines to drive down wages were simply the most accessible targets for expressions of anger and direct action.
The Luddites were not the first or only machine wreckers. Because organized, large-scale strikes were impractical due to the scattering of manufactories throughout different regions, machine wrecking, which E. J. Hobsbawm calls "collective bargaining by riot," had occurred in Britain since the Restoration. For example, in 1675 Spitalfields narrow weavers destroyed "engines," power machines that could each do the work of several people, and in 1710 a London hosier employing too many apprentices in violation of the Framework Knitters Charter had his machines broken by angry stockingers. Even parliamentary action in 1727, making the destruction of machines a capital felony, did little to stop the activity. In 1768 London sawyers attacked a mechanized sawmill. Following the failure in 1778 of the stockingers' petitions to Parliament to enact a law regulating "the Art and Mystery of Framework Knitting," Nottingham workers rioted, flinging machines into the streets. In 1792 Manchester weavers destroyed two dozen Cartwright steam looms owned by George Grimshaw. Sporadic attacks on machines (wide knitting frames, gig mills, shearing frames, and steam-powered looms and spinning jennies) continued, especially from 1799 to 1802 and through the period of economic distress after 1808. http://campus.murraystate.edu/academic/faculty/kevin.binfield/luddites/LudditeHistory.htmWhat the above essay doesn't touch on was the use of Enclosure to drive formerly self-sustaining populations into the factories in the first place.
