What would you change about the US government if you could start from scratch?

The Bill of Rights should include one or more amendments protecting our economic freedoms, in addition to the existing amendments protecting personal freedoms. It should include the following rules:

[ul]
[li]The government may not establish any maximum or minimum price for the sale of any item.[/li][li]The government may not force the American people to purchase anything.[/li][li]The government may not pass any law specifically designed to favor any one private corporation or union.[/li][li]The government may not prohibit anyone from buying or selling anything, except for the following reasons: the sale is fraudulent, the item in question threatens someone’s physical safety[/li][li]No one may be forced to join a union.[/li][/ul]
