It make sense on the long run, think about it, technology introduced new jobs to offset the ones it killed
But as we get better doing what we do, as we become more efficient we need less people to do a particular job.
Now without new types of Jobs being created by new technology, efficiency can net kill jobs
Another point to consider is that other factors are surely at play that accelerated the net killing of job, such as outsourcing and so on (outsourcing of course, is make available because of advancement in IT and communication)
