We should have no illusions about the work ahead of us. Reforming our schools; changing the way we use energy; reducing our deficit – none of this is easy. All of it will take time. And it will be harder because we will argue about everything. The cost. The details. The letter of every law.
Of course, some countries don't have this problem. If the central government wants a railroad, they get a railroad – no matter how many homes are bulldozed. If they don't want a bad story in the newspaper, it doesn't get written.
And yet, as contentious and frustrating and messy as our democracy can sometimes be, I know there isn't a person here who would trade places with any other nation on Earth.
