I honestly think the two aren't linked. At least not as cause and effect, at least. Multinational investment drove the growth, but it was property madness that drove the bubble. So when the global economy faltered, there was a downturn in foreign investment - but it was the property bubble that burst.
I can still say that almost everyone I know here works for a multinational. So while they seem to artificially expand GDP (a huge amount of our GDP isn't actually domestic, and doesn't benefit us the same way domestic product would) - for us little folk on the ground, they still mean a lot, lot more jobs than we'd have otherwise.
How we actually domesticate this investment so it's not at risk of just flitting off to the next cheap destination, I have no idea. But I think that's the real long-term risk & challenge, not the stupid amounts of imaginary money people had pinned on the property bubble.
