Excellent advice for those who would understand either American politics or economics in general. Read PJ O'Rourke . Greg Mankiw (who teaches the ec.10 course at Harvard) has been known to add him to his reading lists.
For those who would go a little deeper, another recomendation. Hernando de Soto manages to explain  more about why some places grow and others don't.
Gary Becker  explains something about the sub prime crisis: it can't have been a plot by predatory lenders, as it's the lenders who are losing the money (unless said lenders were in fact insanely stupid which would be a rather different problem).
(Sweary alert) We have the usual sight  of politicians being generous with our money, not so much with their own.
A thought on social democracies and their high tax rates  : how do you keep them (both the taxes and the citizens subject to them) when emigration becomes ever easier?
One way the net is changing the world: making  the oddest of hobbies easier.
And finally  , Bah Hecate! to the whole Christmas thing.
