I do that too!

(Long time no see, old friend.)

Excuse me? Is the former chairman of Sears on hacker news?

But the type of organization that is a corporation didn't exist when the constitution was written. Much like nuclear arms (and chemical, and biological) didn't exist when the constitution was written so we don't consider them covered by the second amendment.

It certainly did. Among others, the Virginia Company, the Plymouth Company, the British East India Company all featured tradeable shares, perpetual lifetime, limited liability and legal personhood.

What makes the modern economy so different is the democraticization of incorporation. Prior to the 19th century it took a specific legislative act to incorporate.

Maybe that's something we need to bring back -- limits on how many and how large corporations can be? Before they take over running all of society?

Right now you can create infinite corporations, with little to no traceability as to who's really responsible. Maybe there should be some limits?

British East India company had its own army and literally did run a big part of society. Amazon doesn’t have an army at least. Maybe we are trending in the right direction.

We don't consider nuclear warheads to be covered under the second amendment because they are munitions, not arms. What you're saying is a little ridiculous - do you expect that something written on the Internet is not covered by the first amendment, simply because it didn't exist at the time the amendment was written? Of course not. Technological progress is easily covered by the Constitution.

The English East India Company was set up along lines pretty similar to today's corporations, and that happened almost 200 years before the constitution was written (1600, to be precise). By 1720 you definitely have bubbles involving corporate stocks (see South Sea Bubble).

By the time you get to the late 18th century (i.e. about when the Constitution was written) you have publications with titles like "A Treatise on the Law of Corporations"; just keep reading the Wikipedia entry above. That was published 7 years after the US Constitution was ratified, but of course the laws and corporations it was talking abot had been around for _quite_ a while at that point.

Joint stock corporations predate the US constitution.
