elaborate on this: The underlying problem in this case from Amtrak CEO Richard Anderson's perspective is the financial sustainability of the company. Amtrak is a passenger rail service that is funded by the government, but it is still required to operate in a financially responsible manner. The company has been struggling to break even for many years, and CEO Anderson is trying to find ways to make the company more financially sustainable. Some of the causes of this problem include the fact that passenger rail service is not as financially lucrative as other forms of transportation, such as air travel. Additionally, Amtrak is required to provide service to rural areas that are not as densely populated, which can make it difficult to generate enough revenue to cover costs.
