The U.S. Dollar has been going down against other currencies since April, 2002. Whomever touts parity with the Canadian Dollar as news hasn't been watching as we got ourselves into this mess. You have to go back more than 35 years to find a time when the Dollar was worth less than it is now.
Now we need to turn it around and make the greenback worth something. One way to do help is by not spending so much overseas. Just a thought.
