What issues do you think are most important

[Chaerophon]

So, in your own Einstein-like mind, how do you figure that the US has been able to accomlish all that it has

First of all, I'm not of the opinion that Americans are, in general, 'stupider' than are the people of any other nation.

But, as a counter to what is implied by the rest of your posts in this thread, I'll clear up the above. A few contributing factors were: abundant access to resources. High population. Distance from military attack. British market as a source for early development. Inherited heritage of merfcantilist/capitalist development strategies. Not because they are inherently 'smarter'. They may be comparatively 'smart' now, when compared to less developed countries, as a result of the infrastructural developments facilitated by factors such as these.

Of course, I've just given you an opportunity to yap some more. I'd hate to have to make you look foolish again, but, have at 'er if you will.

EDITED: too 'absolute' in tone. Addressed as per criticisms. Plenty of room for other factors; however, inherent 'smarts' is not one of them.
