That is a good questions and I do not have an answer. We often hear about factories being opened and creating jobs, be it car assembly plants, or something else.
Ten the other side of the coin are the high tech jobs that require Masters Degress in Computer Science, Business, Economics, Law, etc.
The only thing left are car sales and insurance sales and the minimum wage jobs at convenience stores and the like.
I am nearing 61. I have been out of work 15 months. I have applied for more than 120 jobs. Had about 10 interviews. My work history includes two jobs in the last 35 years as a newspaper reporter and as a public relations director. I have apparently passed my prime no one is interested in training an "old man" like me to take on a new job.
It is going to be interesting, 30 years from now--I will not be around, and the job force is composed of people in 60 year range who have jumped from job to job to job. How hard is it going to be for them to find a job.
