> One is that money makes people inherently happy. Which is so obviously wrong it's not even worth talking about.

Really. The mere fact of having large chunk of cash and resources, without necessarily even spending it as such - per say, can make people inherently happy-ier.

I'll give you an example: You can say NO whenever you wish. It reduces stress without having spent a single penny of it. It changes your attitude to life by mere fact of having it. Even if don't say NO (because situation doesn't call for it), having the mere option to say it at any given moment - makes you inherently happier and have a healthier attitude to life.

So not even this point stands. Money can make people inherently happy-ier. Without as much as even spending a penny extra as you would have had before you got the "big stash".
