Because non-hispanics are justifiably AFRAID to be out in the fields with the hispanics that think they OWN the labor rights.
This article is such BS propaganda! Berry field owners in the US are using an extremely inefficient labor model. Workers stoop and carry boxes back and forth. Europe and New Zealand, for example, produce berries and there the (lesser numbered and better paid) pickers recline on mobile carriers that allow them to pick more per hour and not get worn out.
the berry farmer in this article is just rationaling his poor practices--at our national expense.
Sounds good. I'd never heard of that!! Do you have any links with pictures? I just love applications of mechanical ingenuity :o)
