We're arguing about general trends, where there is a whole spectrum of
situations, so it's probably difficult to establish anything, but here
are some more comments.

It seems to me that even when you are not successful, there is always
"some kind of place" for you in any society, but it may be very
humble, and even quite unfree. People are always eager to dominate one
another, so if you're not successful they will be glad to manage a
dominated slot in the society for you.

It takes some openness, self-confidence, pride and adventurous
attitude to go, even when your present condition is bad. And if you're
really dieing, then you cannot even go.

Of course the case of British convicts taken to Australia is special,
as it is not a free act. Choosing to leave because you are too poor or
you don't like life here, on the contrary, is a free act.

I never said "best" or "brightest". European elites are much brighter
that American elites, for example ;-) I'm referring to a disposition
to embark in the unknown with hope to make your situation better.

If you consider this disposition as brightness, well, that's because
you're American :-)

Some risk-taking / self-confidence / taste for the unknown do not
result in self-selection, but migration does.

That was not self-selection, but artificial selection performed by the
Americans based on external properties.

However good "good" is, it can still be better. You have extra
incentive to go if your life is bad, but even if it's good you may be
tempted to make it even better, if that's how your mind works.

Some kind of convictions may be for some the support of
self-confidence. You know that everything will be different there --
but at least you can rely on yourself, you know who you are, what are
good and bad, etc.

What I was saying is, you can NOW correlate these things. You have
self-selection through migration (with the possible pressure of
difficult conditions), and then success resulting, over time, from the
selected behaviour.

One obvious OTHER FACTOR (for the "success of the settler") is that
everytime you have to REDO something, you have occasion to do it
better. So when you arrive in a land with nothing established, you have
to re-think every single thing, and so you question what you know,
and you make it better.

Though on the other hand, one could say that you tend to dismiss too
easily things (like social institutions, or moral conduct, or
politeness forms) that have grown over time, as you are not able to
grasp their intricate usefullness when you redesign things from scratch.

One can probably also witness this occasional shortcoming in the US
society.

It may be the source of the impression of naïvety that Europeans
(French at least) sometimes have when examining American behaviour or
discourse. There is a fine line between naïvety and freedom from
tradition / openness to new solutions.
