> I don't really see how this new data contradicts the generally accepted view (mentioned in the article) that money increases happiness up to a point.

It doesn't - the title of the article and the interpretation provided with in is almost as misleading. They start off quickly by telling you about the 'Easterlin paradox' - that is what they have specifically found evidence against. i.e. 'more money makes you happier' is backed by evidence.

The fact that more money makes you happier does not mean that any amount of money can make you as happy as you want though...

This is not surprising - its probably common sense.
