Teenagers today are not the same as they were when you were a teenager, and farms cannot rely on teenagers to do the work.
Funny you mention that . In my parents neighborhood there are several families with teenagers but guess who I see cutting the grass in the neighborhoods. Lawn Care Services and the employees seem to be of Hispanic descent. I am 20 years old and I have to say that alot of the kids I grew up would never be caught dead working in a Mcdonalds, it would ruin their image I guess. The ideal job for those teens is working at the mall preferabbly in a store and not the food counter. When I think about it the mall eatery employees tend to be asian and hispanic.
I think it depends on where in the country you are.
I'm going to go further and say that the more affluent the part of the country you are in, the less likely those teenagers will be cutting grass and working at fast food restaurants.
You'll NEVER find any teenagers cutting grass or working at fast food restaurants here in Northern Virginia where a typical single-family home sets you back half a million, but in Hanover, PA where that same single-family home might cost $150K, you WILL indeed find teenagers cutting grass and working at fast food restaurants.
Frankly, what I see happening in Northern Virginia is the erosion of the middle class--what is middle class in much of the rest of the country simply cannot afford to live here anymore. So now you have the "upper class" (whose teenage offspring wouldn't degrade themselves by working those "crap jobs") and the "lower/servant class" (who does all of the "crap jobs").
Sounds like that two-tier society that works so well in other countries.
Oh, if you're wondering how the "lower/servant class" can manage to afford to live here, wonder no more: They just overcrowd houses. 3 bedrooms, 8 people, that sort of thing.
Oh, Kerry won Fairfax County (Northern Virginia's most populous county, which Bush won in 2000) and I also believe that areas without a strong middle class presence tend to swing to the left, politically. Washington, DC is a fine example, Bush won 9% of the vote there.
I predict that Fairfax County will start turning bluer and bluer as the years go on.
