I'm sure the analysis could be expanded – why don't you give your try at an essay? If you write it, I'll read it. How much should the essay be expanded? Surely we don't want a 1:1 scale model of reality. We probably should not factor in the conductivity of water and compare against the cost of 1 liter of milk; although if I wanted to attack the integrity of the essay I might lament those factors' absence. Snark aside, I like that the author chose to compare Switzerland, Germany, and the US. It elegantly illustrated the similarities and differences.
