It has nothing to do with respect. Parents in most cases do not understand technology, much less programming whereas they can understand what an attorney or doctor does. The lawyer can keep you out of jail. The doctor can keep you from dying. What the heck does a programmer do that's so important? Note - I'm a programmer. I'm just look at it from their position. Then again, I live in Silicon Valley. When I say I write iPhone apps nobody looks down on me --- in fact quite the opposite.
