Phrase choice - phrase to describe exodus of meaningful celebrities from Australia [closed]

Most meaningful socialites seem to leave Australia, leaving us with celebrity cooks and celebrity hairdressers. (eg Elle McPherson and Savage Garden going to London etc). What's the phrase to describe the exodus of meaningful celebrities from Australia?

Is this "post-colonial parochialism"? "First-world elitism?" Or is it just "Global Capitalism"?

I don't think you need a phrase for this: "exodus of meaningful celebrities" is already perfect, with its strong hint of oxymoronicism spiced with biblical exaggeration.

Perhaps a "golgafrincham" is the word, although technically it's not quite correct. But it doesnt hold a candle to the "meaningful celebrities" gag.

Maybe it's the vain drain? Or the cocaine drain?

Since the sentence you've constructed intends to contrast the behavior of Aussie's who've gained international notoriety and the behavior of Aussie's whose fame exists only within their homeland, it seems preferable to simply state your distinction on those terms. After all, since contrast is basic to your construction, calling one group meaningful implies that the other is not. And I doubt that's built in, really, to what you're meaning to convey.

Here's what it looks like you intend, if you'll allow for the split infinitive:

As soon as mega-talented Aussies gain international fame, generally speaking, they seem content to abandon our shores and leave Australia in the trusty hands of celebrity hairdressers and celebrity cooks.

Beyond this, what you're asking for somewhat eludes me. Are you looking for a title, a phrase to use in another sentence referring back to this one, a replacement for the term meaningful socialites in this sentence, or, more broadly, just a way to talk about the phenomenon?
