What types of generalizations did Mayhew make about the London street people and how did this reflect Victorian thinking on industrialization?

Mayhew made sweeping generalizations about the different types of street people, and often relied on stereotypes. For example, he claimed that all blind musicians were highly religious while all "mechanics" or skilled laborers were melancholy, suffering from chronic depression. This reflected the Victorian belief that machines, cities and industrialization in general were unhealthy, at least for the lower classes.
