Don't believe any of them, polls are never accurate, maybe they all are biased.

As for my opinion, well I'm happy here, and all I see are Happy Smiling Pinoy Faces.

As for prosperous countries, I think they are too busy trying to earn income to pay loans, car, house, furniture and holidays etc, not forgetting the credit card payments. Is that happy? I think not, more like the Ostrich with its head in the sand.
