today in class

today we did an activity about reserved, emmunated (sp?) and concurrent powers. I got most of the venn diagram correct, except for the school standards one, I thought that only states could establish school standards, but today I learned that even though Massachusetts is the best in the nation, the national government decided to take that matter into their own hands. We're learning about the case of the national bank or state bank and I said we should have one national bank, so we don't have to worry about fees that come with using a different bank then your own. And if the bank was for the entire country, then there wouldn't be worries that the bank would go bankrupt because all the banks would be the same and there wouldn't be much competition. I guess that's how I think of it, I'm not quite sure if these are valid reasons, I guess I don't really understand it.
