Very true, and while few people would make a career out of pumping gas or being a bus conductor, a lot of people used those types of jobs to support them while working their way through uni. What do they do now ? Some may have a partner who is working, or parents that support them but a lot of others just can't afford to go to uni and can't get a job because they have no qualifications.
We are losing generations of workers to technological change, but we still bring in people from overseas in droves. Crazy.
No doubt if innovations and new technology had not taken place as far as self service at the servo, banks and the like, cost of consumer goods may have been higher than they now.
Why are you still pushing your barrow on bringing in overseas workers.......we have been through this before as to the reasons why.....we cannot get our Aussies to leave the comfort of city life to work in remote areas...we cannot get Aussie workers to go and pick fruit because it is too hard work so we allow back packers in on working visas who are not afraid of hard work.
I do hope we don't have to go through this megalomania again Rumpy.
