The American Recovery and Reinvestment Act of 2009 was an example of a situation leadership style. The U.S. was coming off a recession so people looked up to Obama to fix everything and get things moving again in the U.S. This was appropriate to use because the U.S. was coming off of some rough times financially so in this situation I think it was valid to act on. Critics might disagree because they think that he should have acted sooner because it took a year to get the job done and that he should have acted a lot sooner.
The path-goal theory could have been used in this situation by stating a clear path on how they will fix the issue on hand and in return the american people could be happier and safe. This would have been appropriate because it could have given the people of america a clear plan on when and how things will get done. Critics might disagree because this plan could often get criticized for being too long of a process.
I would have used the situational leadership style in this particular scenario. This was probably the most effective strategy because as a country the people needed an effective move because of the recession currently in the country. The only thing I think would have been better was if the situation was fixed faster instead of a year later.
