The 14th Amendment has been invoked far more times to grant corporations the rights normally only allotted to citizens than by blacks to get the same rights as whites.
That demonstrates a pretty anti-business worldview on your part. Are you sure you're on the right forum?
Depends on the definition of a corporation. Business and “corporation” are not necessarily synonymous.
I am opposed to crony capitalism as most people on FR seem to be these days. Except, of course, for those few naive useful idiots in the libertarian camp who think everything will work out in the wash if corporations are allowed to do whatever they please.
