Which clause gives congress the power to make any laws that are deemed "necessary and proper" to carry out all the other powers of government?

The answer is the Necessary and Proper clause or also known as the elastic clause. This found in Article 1, Section 8, Clause 18. It is stated there that, “The Congress shall have Power To ...make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof.” In short, this allows the Congress to make laws it needs to carry out its own powers. Also, it grants Congress the powers that are inferred in the Constitution, but that are not explicitly stated. That is why the powers which is from the Necessary and Proper Clause are denoted to as implied powers.

panem is a communist totalitarian dictatorship where all the resources and how they are allocated belongs to the capitol. the districts exist only to provide goods and services for the capital and most of the citizens live in poverty. it is a police state where the "peacekeepers" use force and threats to keep the people under control. dissent is outlawed and those who disobey the law are executed, flogged, or turned into avoxes. the games are another means in which the ruling elite in the capitol exert their power over the districts. when reading the books i drew parallels between panem and the soviet union and north korea. in no way is panem capitalist. the people in the capitol are wealthy but the majority of them are involved in the government somehow. it was the same way in the former soviet union where bigwigs in the communist party and high ranking government officials were given access to goods, services, medical treatments not available to the general public. if you think panem has a capitalist economy you need to brush up on your economics.
