Final answer:
In the speech by President George W. Bush during the 2008 financial crisis, he has credentials and experience, but the speech lacks direct citation of experts or data and does not provide a variety of sources to support his claims. It is more of a reassurance to the public rather than an analytical breakdown of the situation with empirical backing.
Step-by-step explanation:
When evaluating the validity of the primary source which is the speech made by President George W. Bush in September of 2008, one can ascertain that the speaker, as the President of the United States, has credentials and experience in the issues discussed. President Bush's speech came during a pivotal moment in American financial history, characterized by the 2008 financial crisis, where major institutions failed, and stock market volatility signaled deep economic troubles.
However, this particular excerpt from Bush's speech does not cite experts or data to support the claims, nor does it provide a variety of sources for support. Instead, it seeks to reassure the nation by expressing that the federal government is taking decisive action and has a history of overcoming such challenges.
In this context, it is clear that the President is utilizing his position and the authority it commands to assert a perspective.
This differs from other events in history, such as President Franklin D. Roosevelt's fireside chats during the Great Depression, where confidence-building and explicit detailing of policy were crucial. Similarly, President Bill Clinton's communication with the public during economic hardship centered around addressing the immediate concerns of average Americans and proposing clear policy initiatives.
Hence, President Bush's speech can be seen as more of a reassurance effort, without the empirical backing that might come from citing expert data or presenting a variety of sources.
