1. For the first one here the missing part would be Supreme Court. Article II of the Constitution establishes a single Supreme Court. In the Constitution it says :"The Judicial Power of the United States shall be vested in one supreme Court". To power to interpret the laws lays within the Supreme Court and the inferior courts.
2. The power to create lower courts, that is "inferior" courts is vested to the Congress of the United States. As it says in Article III: " and in such inferior Courts as the Congress may from time to time ordain and establish." The lower courts that the Congress establishes are inferior to the Supreme Court and thus are termed "inferior", the rulings of the Supreme Court apply to all lower courts.
Mass production of goods resulted in the use of mechanization to have an oversupply. Some labor work were replaced by machines, which created unemployment and change of needed skills for an upgrade.

There is no key to civilization. The concept that native americans did not have a civilization or were not civilized is one only supported by the egotism and arrogance of the empirical profit oriented "conquerers" who have worked to eradicate all cultures that conflict with profits. The key to western civilization that allowed them to kill off the majority of the natives was a lack of respect for life and insane drive for control, ownership and dominance, to which the peaceful and sophisticated Natives would not stoop.
They want their products cuz China didn't pay them
