Obamas Inaugural Address

Next month president-elect Obama will be giving his Inaugural speech. As I was reading about his Chief Speechwriter I came across this..
"Last month, Favreau met for an hour in Chicago with Obama and adviser David Axelrod, as is their habit before important speeches. Obama told him to make the inaugural address no longer than 15 or 20 minutes, and they agreed to theme it around, Favreau said, "this moment that we're in, and the idea that America was founded on certain ideals that we need to take back." Obama asked for a first draft by Thanksgiving. Favreau explained that he had planned a vacation and promised a draft by this week."
As I read this I thought to myself what was America founded on? We were founded on taking advantage of Indians sustaining a way of living. We were founded on not making "every man equal." We were founded on not giving women rights except for the right to produce babies and cook. Most of these ideals have disappeared throughout the years, but they are still what this country was built on and why would we want to consider those ideals again. It might just be me, but the United States was not built on great ideals and there should be no reason why we shouldn't just look towards the future and make new ideals. It does not make sense to me that we would do this. I hope that Mr. Obama and Mr. Favreau is smart enough and is just addressing this issue rather than explaining why is should be in affect.
