Which of the following statements best describes the state of America's labor movement during the early decades of the 19^th century?

A) Wage earners quickly became the wealthy middle-class.
B) Workers in industrial cities benefitted the most from wage labor.
C) Strikes were used as a first resort to address labor issues.
D) Neighborhoods became defined by class.

During the early decades of the 20th century, America's labor movement was marked by significant class distinctions, which often manifested in the way neighborhoods were organized and defined. Industrialization and urbanization led to the concentration of wealth in certain areas, while workers and their families often lived in less affluent, more densely populated neighborhoods. This period did not see wage earners quickly becoming wealthy, nor did all workers in industrial cities benefit equally from wage labor. Strikes were more often a last resort after other methods of negotiation failed, rather than a first resort.
