Mick,
There are alternatives to just knocking things down again! One suggestion is Habitat for Humanity to consider. This organisation assists folks on a lower income to become independent home owners.
This is an interesting thread. I'm a computer boffin myself and have been for twenty years. This industry used to run on a de facto apprenticeship system. People like me were taken on because universities were not able to churn out graduates out fast enough. This doesn't happen anymore.
Entry level jobs are now almost exclusively occupied by Computer Science or Information Technology graduates. I personally don't have a problem with that. The young adults that come out of university now are far better prepared than I was educationally but are no better prepared emotionally, on average, than 22 and 23 year olds were 20 years ago. No surprise there.
I am concerned about their middle-career prospects though. They will face increasing competition for the work they can do by overseas contractors. The problem for us as a country and managers of organisations is where the next level of professionals are going to come from in 20 years if the careers of these people has no middle level progression?
The way things are going my kids, as you said (or someone said anyway), might be better off (I'm talking about from a purely financial point of view) being carpenters or another skilled trade. I have seen this in other professions. The profession we all love, lawyers (cough) are going through turmoil as well. My nephew graduated from Macquarie University. He's a fully trained solicitor and has gone to England because he can't get a job here. I doubt he will return.
Rambling on a bit, I know but I'm still feeling a little raw myself with the "life changing" career experiences of the last 12 months...
