About Soulmates and Jobs

Searching for a soulmate is like searching for a job. Just as when you look for a job, you weigh the good and bad things about it and settle for a middle ground, same is true when you are looking for a soulmate. Atleast that's what Betsey Stevenson believes. In a commentary for Marketplace she writes:

Economists simply can't believe in one soulmate. There are too many people in the world and the odds of finding that one person in five billion are, well, you can do the math.

So if economists don't believe in soulmates, why do we think people get married?

Searching for a spouse is very similar to searching for a job. There is not one perfect job for each of us, but there are clearly better and worse jobs. So we hunt, for a spouse and a job. When do we stop? When the offer in the hand is better than the likely offer in the bush.
