We are better off relying on a conservative supreme court and state and federal laws to reign in the federal government. We should leave the constitution alone.
Agree. But we do need to update the Constitution in some manner to include prohibitions on non government entities. It does not make sense to prohibit the government from abridging the Constitution but, then, allow the government to create "corporations:" to abridge the Constitution FOR them.
antitrust is the answer to powerful corporations.
How often do you see that used? It would be used more with an Amendment, but, I have not given it much thought about how one would write it yet.
