What else is a corporation then?

Legal fiction. It was convenient to treat them as persons for legal reasons, but it's now clear that we need to clarify that with an amendment.

As far as I can tell, a corporation is already not treated as a literal person, only it has some of the same rights. Simplest example, a corporation can't run for a public office. What do you suggest should be changed, no 1A for a corporation?

Yes, corporations are not people, and do not get rights, period. They're legal fictions that get privileges that we the people grant them.

If you want to represent yourself commercially as a person, your rights as a person can be extended to that legal fiction.

If you want legal fiction that you can dump when it's convenient and isn't tied to you as a person, then that legal fiction gets no rights and only certain privileges.

A legal fiction.

So since 1886?
