ELI5: Why are corporations considered a person and why was it necessary to implement this?
gpt
Corporations are not people, as much as some politicians and pundits would like you to believe, however, in order to do business, they have to be granted some of the same rights as people. People and pets have the right to not be physically abused, but that doesn't make pets people.

As a REPRESENTATIVE of a group of people, a corporation needs the ability to do things like enter into contracts, be taxed and act as a single entity for a group of people. Corporations also shield individuals from the liabilities of a company. If a company goes bankrupt, the debtors can't take money away from the individual shareholders. 

Basically, a corporation is a legal construct to allow a group of people (shareholders) do business.
