Right, let me clarify. Let's define three realms of experience for the sake of conversation: (physical/material), (emotional), (intellectual). For simplicity let's assume that all human experiences may be categorised thus.

Now, what can money buy? Only things on the physical level, that is, _sense experiences_. Sights, sounds, smells, tastes and touches. That's it. Money can't buy love or knowledge. Maybe a library, but not knowledge :)

So even in a naive examination money has limited uses which apply at the physical/material level. It's useful to note that happiness/wellbeing is largely a state of mind and thus you might find someone who is equally or more happy than you despite not having the generator. How is this possible?

The point is that as inherent motivation money just isn't good. People who are incentivised inevitably want greater and greater compensation or they burn out. In contrast, those fired up by a higher ideal (which, of course, includes the wellbeing of the family) are motivated by an initiative to work which is not dependent upon something external.

So, make your money, and install that generator. But don't make the mistake of thinking your wellbeing/happiness is dependent upon XYZ externally.
