Jobs have become de-skilled, staff have been cut and the checks and balances of old have gone out the window.
Furthermore, junior staff had training, career progression and other incentives. You would get a decent pension and you were regarded as a professional. Not the sort of things you threw away lightly for a few quick bucks?
Boy, I think you've summed up the root cause of a grand multitude of IT and IT security problems abroad right there.

Today you have more and more IT people not knowing what they're doing, yet in charge of a volume of sensitive data. In their defense (as I've been that ignorant IT person myself in past jobs), the problem is often a lack of training as opposed to a lack of competence. No one's seriously investing in them.

And consequently, IT is no longer (if it ever was) a well regarded profession. Ya know, there's a world of difference between "IT Professional" and "computer guy", and nowadays everyone is seen as the latter.
