It's not bullshit, it's interesting. But comparing this result to the previous results is not valid considering the very strong framing device they used to get that result. They are basically getting people to judge their happiness against a hypothetical future rich self, when we already know that people have a bias to assuming more money would make them much happier than it actually would. If I wanted to "prove" money made you happier I would construct a poll exactly like this (or at least I hope I would have been smart enough to come up with this). The fact that it worked is still interesting however.
