The Constitution fixed the problems of the Articles of
Confederation by the following. Article I of the Constitution, Congress
can regulate interstate commerce. It is also responsible for coinage and
only Congress can regulate tariffs; in the early days of the national government,
it was largely funded through land sales, excise taxes, and tariffs.
Article II gave the national government a chief executive whose job it
was to execute the laws. He had veto power over Congress, but Congress
could override his veto or even vote to impeach him in extreme cases.
The plague likely started in Asia and traveled westward along the Silk Road. The disease was carried by fleas that lived on rats.
Americans developed a widespread fear of Communist infiltration into the American government or of an anarchist or communist revolution that could overthrow the prevailing capitalist order in the United States by imposing a Communist dictatorship, just as in the USSR. This diffuse dread gave way to aggressive investigations and the arrest of people ideologically suspicious or otherwise associated with communist or socialist movements. At that moment, the citizens would become distrustful and afraid of being denounced as a communist sympathizer because that would imply in being persecuted by the government and having their civic guarantees withdrawn.
