women's rights in the 1800s
In the early 1800s, women were second-class citizens. ... Women were not encouraged to obtain a real education or pursue a professional career. After marriage, women did not have the right to own their own property, keep their own wages, or sign a contract. In addition, all women were denied the right tovote.
On May 10, 1869, at Promontory Point, Utah, workers drove a spike that linked two rail lines, one snaking from the East, the other from California, completing America's first transcontinental railroad. This event helped launch an era of economic development that would transform a Jeffersonian society of yeoman farmers into an industrial powerhouse.
They created more jobs to better the economy. These jobs mostly in manufacturing as that would be best for the war effort.
If they produce too many things and the demand is low they will have to lower their prices/pay workers less to make them.
