I'm not so sure here. Young kids recently seem to act like know-it-alls who hate conforming the group environment; everything you do they see as being done the wrong way as it's not the same as what they did on their last job or what their professor talked about. Older workers, or those of a certain age, had to learn by necessity to learn new tools and discard old ones on a regular basis, and ever new job they took required them to learn to adapt to the new situation.
The older workers can be molded because they have plenty of experience with being molded. The younger workers still have this idealistic vision of how everything should be done. Older workers have patience earned through experience, and it's much more common for me to see the younger workers as the ones who are easily frustrated.
The kids are the ones who only write in their preferred language in my experience, which is probably the only language they know.
