This is a little disingenuous:
The founders of this nation warned about the dangers of corporate influence. The Constitution they wrote mentions many things and assigns them rights and protections — the people, militias, the press, religions. But it does not mention corporations.
From this NYT editorial on the campaign finance ruling. The founders of this nation did no such thing. They warned about the dangers of faction, by which they meant political parties. (That warning was forgotten, like, instantly.) The reason they didn’t warn about corporations, or include mention of them in the Constitution, is because corporations didn’t exist back then. At least, not like we understand them today. If you wanted to start a company in 1800 you needed a charter from the legislature, and even then you had to dissolve when the purpose of your charter was fulfilled. Nowadays you just go over to legalzoom.com and click on a few things.
Historical fun fact! One time, Aaron Burr started a company to run the water works of New York City, but he sneaked some language into the charter bill that gave the company a bit of a wider purpose than he said he needed, and with that he started the Bank of Manhattan! People were pissed. That was the main reason everyone thought Burr was an asshole, until that other thing happened.
