As Thom Hartmann has explained at length, the meaning of the Fourteenth Amendment got radically expanded almost 20 years after it was ratified. In the written decision for an 1886 Supreme Court case reviewing how railroads could be taxed, Santa Clara County v. Southern Pacific Railroad, the headnotes recorded that Chief Justice Morrison Waite asserted during arguments that we are all of the opinion that the Fourteenth Amendment applies to these corporations. That language, which wasnt even part of the decisions central holding, has in turn been used as precedent and to force legislatures to treat corporations the same as human people.
Without the 14th amendment, corporations would no longer enjoy 1st-amendment-rights, like unlimited donations and religious freedom...
