A major goal of Henry Clay's American System was to promote industry through improving transportation. This can be seen through his plan to develop a system of internal improvements, such as roads and canals, which would connect the country together and would receive it's money from tariff and land sales revenue. 5.0
Labor unions were greatly influenced by the massive amounts of immigration that took place during this time in the sense that lots of the immigrants were workers who were being treated unfairly by factory owners. This of course also affected government actions, as the government had to deal with the unions.
I think the labor market is the nominal market in which workers find paying work, employers find willing workers, and wage rates are determined.
The main way in which social scientist interpret the past is by looking
at huma interactions--how humans have evolved to deal and create things
like economies and social norms.
Hope it helped : )
