Why is it good to create jobs?
In general, it is not:


  Despite the focus on ‘jobism’, jobs are a cost of production and
  consumption, not a benefit, and should be minimized


Mark J. Perry @ AEI 


  Public discourse tends to be carried out in terms of jobs, as if a great objective was to create jobs. Now that’s not our objective at
  all. There’s no problem about creating jobs. We can create any number
  of jobs in having people dig holes and fill them up again. Do we want
  jobs like that? No. Jobs are a price and we have to work to live.
  Whereas if you listen to the terminology you would think that we live
  to work. Now some of us do. There are workaholics just like there are
  alcoholics and some of us do live to work. But in the main, what we
  want is not jobs, but productive jobs. We want jobs that will be able
  to produce the goods and services that we consume at a minimum
  expenditure of effort. In a way, the appropriate national objective is
  to have the fewest possible jobs. That is to say, the least amount of
  work for the greatest amount of products.


Milton Friedman in a 1980 lecture 


  Under most circumstances, wages paid to people employed on a project
  should not be counted as benefits, although this practice is
  disturbingly widespread. As mentioned above, the opportunity cost of
  labor used on a project is the output that that labor would have
  generated elsewhere, either in paid work or in household production.
  Including wages paid to labor on a project as a benefit implies that
  that labor would have produced nothing otherwise and that the agency
  making the wage payments does not have standing.


Zerbe and Bellas (page 117-118):

I say in general, because there are some evidence that "jobs are good for you", and if increasing jobs diminishes the number of long term unemployed, that might be considered a benefit, even though it diminishes the quantity of leisure and home production they consume.
