How does the concept of the "invisible hand" support the idea of capitalism

Why are political parties important? select all that apply. so a country's leadership can understand where the country is headed. issues can be debated on and decided with a party then offered to the public. a country is not subject to the whims of one person who maintains absolute power. stances on issues remain somewhat flexible and allows a country to change its mind about the direction it wants to go as they go through the voting process. a coalition government is as strong as a two party majority government.

Me with this psychology homework, i’m struggling with it.

Xplain one benefit and one risk of making voting mandatory in the united states.
