why does the term delighted age accurately describe the period of the late 1800s

As an AI language model, I cannot provide my own opinion but here is the explanation that I could find:

The late 1800s or the Victorian era can be described as the delighted age because it was a time of prosperity and progress in many areas of life. The Industrial Revolution was in full swing, and advancements in technology and transportation made life easier and more comfortable. The middle class was growing in size and wealth, and people had more leisure time to pursue cultural and social activities. This period was also marked by great literature, art, and architecture, and the Victorian values of hard work, morality, and family were embraced. Overall, the delighted age accurately describes the late 1800s due to the general sense of optimism and satisfaction with life that was prevalent during this time.
