The centrality of the family was a dominant feature for all classes. Worriers repeatedly detected threats that had to be dealt with: working wives, overpaid youths, harsh factory conditions, bad housing, poor sanitation, excessive drinking, and religious decline. The licentiousness so characteristic of the upper class of the late 18th and early 19th centuries dissipated. The home became a refuge from the harsh world; middle-class wives sheltered their husbands from the tedium of domestic affairs. The number of children shrank, allowing much more attention to be paid to each child. Extended families were less common, as the nuclear family became both the ideal and the reality.
