The Industrial Revolution brought a large number of cheap manufactured goods to consumers, easing their lives and lifestyles and raising the quality of life that they enjoyed in many ways.
While it came with a human cost, the economic progress the IR represents jobs by the hundreds of thousands, opportunities for immigrants to women, and in the long run, it was a vehicle for social change.
The Industrial Revolution was a blessing because it made a higher standard of living available to a larger number of people. It did this by making goods more cheaply. This allowed more people to afford those goods.
When industrialization came, goods could be made more cheaply. For example, instead of having a skilled workman making pairs of shoes by hand, you could have a semiskilled person using machines to make shoes much more rapidly. Naturally, the price of shoes would go down.
This process happened to more and more goods over time and so more and more goods came to be cheap enough for common people to own them. In this way, the Industrial Revolution was a blessing because it allowed people to be able to afford more goods and a higher standard of living.
