Partly it's because their own educational background doesn't let them develop this kind of pride in their work. Modern education schools' doctrine is that kids don't even need to be taught anything because they can simply "learn everything by themselves" with just a few hints about what sort of 'inquiry' they should undertake. This can seem to "work" well enough for high-achieving students who can always rely on someone (either themselves or family) to pick up the slack; it's invariably a dismal failure for everyone else.
