Why did temperance reformers make one of their main targets the moderate drinkers among the laboring class?

Temperance reformers targeted moderate drinkers among the laboring class because they believed that even moderate consumption contributed to a culture of alcohol dependency and social problems, such as poverty and crime. They viewed these individuals as pivotal in setting an example for others and believed that reducing overall alcohol consumption would lead to improved societal conditions. By focusing on laborers, reformers aimed to uplift the working class and promote healthier lifestyles, which they believed would enhance productivity and community well-being.
