How job requirements have changed in the united states?

Going back to the early 1900's, a majority of average American workers were not highly educated (college degrees were not mandatory), and most worked in factories, or "blue-collar jobs". This continued through the decades until automated machinery took the place of human workers. The more we installed this machinery to do these jobs, the more workers were laid off.

Today, college education is essential for any job. Since nearly all of our production is by machinery, the only people companies look to hire are educated individuals who will work the "white-collar jobs" (office jobs, etc.)

both are true, the congress does have the power to create banks, even if this power is not specifically described in the constitution, since there is nothing restricting it and there is power given to the congress to make "all laws which shall be necessary and proper". maryland was not allowed to tax a branch of the national bank operating there, and the supreme court decided that no state could. both of these topics were discussed in a decision of the mcculloch v. maryland case in 1819.

i believe it is capitalists.
