The Industrial Revolution increased labor hours by two or three times, depending on circumstances. In the sense that they reduced the time for life (leisure) versus the time spent being a cog in the wheel of an industrial system (labor), it certainly eroded living standards.
For a very specific example: the cotton gin likely increased the demand for slave labor in the American South, leading to harsher conditions for slaves, increased acrimony between slaveholders and abolitionists, and eventually the Civil War (the decimation of the Southern economy, the pivot of Northern society to a war footing w/ associated disruptions, and 600,000 Americans dead).
