Wrong - though you're in perfectly respectable company to see things this way.
We don't want jobs, we we don't want products (per se) - we want wealth. A lot of confusion results from not understanding what WEALTH is - it's not money, it's not luxury, it's not even security. The grand-unified (and very values-neutral) definition of wealth is:
A quantity of solved problems.
The problem can be as simple and straightforward as an empty stomach to a sandwich, or as complex as a production line to produce an IPad. What we want is to maximize the quantity of solved problems - this is, almost by definition, how a society solves its problems.
If someone decides that a canal (I've also heard "bridge" and "dam" in the story) is a good and desirable thing, then it is a good and desirable thing because it solves a problem. The goodness and desirability comes from the problem it solves, not by the means that it is achieved. What productivity allows us to do is to solve problems A and B at the same time when before we could only solve problem A with the same resources. It should be clear from this definition that this makes us wealthier: we now have the sandwich AND the IPad production line at the same time.
This definition illucidates a lot of why certain societies developed before others did. "Guns, Germs and Steel" by Jared Diamond is all about this - societies on latitudinally oriented continents were able to take advantage of crops that had developed east and west, making them wealthier. Crops, domesticated animals, cultural practices, even intellectual systems like musical notation - these all represent quantities of solved problems. They therefore constitute wealth.
In short, the jobs are only a means to the end - if we could have food in our stomachs, and canals and IPad production lines WITHOUT jobs, we'd be perfectly happy.
