Except maybe for doctors as I don't have any in my family, the rest are simply trained by their employer. That is hugely different from developer that are expected to not only train themselves at home but also need to research the field to know what they need to train into.

The engineers in my family think I'm a failure because I don't seem to have enough value for my employer that it tries to train me. ( also the "it's just computer programming" that does not help )
