I would say programming is really difficult and it is hard to find competent(pick an arbitrary line in the sand) for any skill let alone programming. Pick a field, and the web is stuffed full of people with battle stories of cleaning up after other people. This is actually a point or two against C++ as the breadth of it is so large. The trick, as in any practice, is to find motivated people willing to learn that are not stubborn in their set ways.
