The biggest enemy of America is the one found within our board rooms, country clubs and high rise corner offices.  The greed and corruption enthroned in those places has been freed from all moral and legal restraint and all people pay the price.  Such is the agenda of modern conservatism.
A strong and stable economy which serves all participants is a worthy goal.  It's achieved by competition tempered with cooperation and justice and by mutually beneficial agreements with other nations not by installing rapist dictators to do the bidding of corporate owners (which always seems to backfire).  Handing corporations the ability to sue any government which acts to protect its' people and environment weakens our own economic opportunities.
We don't achieve a functioning and useful national and world economy by succumbing to atavistic conservative ideologies but by insuring that competent and sane adults have the power to channel the energy of childish greed into beneficial results.
