I've got a somewhat different background and a somewhat different view of the definitions of political action, but what I do see is the absolute need for US schools to teach comparative politics and political systems. I have, for example, never met a Michigan HS grad who had learned in school, for example, how New York State votes, or had questioned why both Germany and the UK have larger legislatures than the US House of Representatives, or why other industrialized nations vote for parties more than individuals, or even that there are other voting methods than "majority rules" (or "first past the post").
Without these comparisons young people grow up to be hopeless, believing that they live in a fixed, unchangeable system.
Every other nation I've been in brings these questions into schools. I wonder why the US does not.
