What If? U.S. constitution is amended, corporations are not persons, money is not speech. Now what?

What would be the major effects?
Would elections change overnight?
Who’s out of business ? Who’s back in business ?

How would the judgements of the Supreme Court of the U.S. be affected?
Are SCOTUS past judgements automatically reviewed in light of the new amendment ?

How long will it take to replace the people now in charge in our governments with people who would apply their energy to different goals than corporate fund-raising?

The media seem to love the status quo, though, how could a un-corporate point-of-view get coverage? The political circus makes people crave more “news”, and political ad revenue looks tasty.

Armagedon ? Nirvana ? Socialism ? Savagery ? The BBC ?
What do you think?
