These seasonal jobs are exactly the kind of jobs needed by younger Americans who haven't been able to find a first-rung of the labor force ladder.
entry-level seasonal jobs would more than likely be as a laundry worker or maid work, which is pretty much making beds and spending half your shift on your knees scrubbing tubs. Hours start at 5 or 6am to 2 or 3pm, which is a direct conflict with college hours. And I'm not sure if today's image-centric yoots would stay with that type of work for a month, much less an entire season. For the unemployed, there are two reasons not to take such work: one, unemployment benefits look back 18 months and a low wage will drag down your average wage; and two, it adds nothing to the resume - a McDonalds' job can at least be painted as team leadership training.
To recover an idea of the honorability of such jobs may be one desideratum.
A problem with our legacy may be that the older generations used to actually boast about how menial their work had been. And that was the wrong attitude. They should have spoken of how God rewarded their progressive effort.
And so in turning from a vice, the younger generations also turned from a virtue as well.
Personally, if I were a manager, and someone coming for an entry level job mentioned honestly that he or she had worked menial jobs and done them honorably enough to not incur spectacular trouble, I would see that as a positive spiritual factor. This is the rudiments, in fact, of the old rags to riches story.
