My point in bringing up the general elitism of hiring is this: people judge reliability, capability, and dedication by all sorts of clues, though the specifics differ by culture. I don't really see a problem with handwriting being one. A dedicated, capable, responsible person will, in a culture where good handwriting is considered a sine qua non of employability, develop excellent handwriting, because they want to be successful and are willing to work at it. In Elizabethan England, a young man wasn't fit for society unless he could join in a song and improvise harmony, and you can bet that the most dedicated, ambitious young men made sure they could do so. Neither is more arbitrary than some of the criteria the American hiring process relies on.
