You must have a really weird theory of political governance. As I peruse history, it does seem to me that how a people are governed (or how they govern themselves) has an absolutely immense effect on happiness and achievement both (and on misery and loss).
On a local level sure, but hopefully not on a federal level in the US. If it is then it is something we ought to look at fixing. It'd kind of mean our constitution isn't working as it should.
