The above may well be half true for younger people just coming out of college or high school but for the older worker it is pure unadulterated fantasy.
I have, in the last year, sent out over 100 resumes, with follow up, written out over 100 applications, with follow up, and have been forced to settle for a part time position, 20 hours a week, simply because of my age.
Companies will not hire a worker over the age of 50 when they are given the choice to hire them or a 23 year old, it just will not happen, regardless of the law against age discrimination.
Obviously the good "doctor" does not realize that or it would denigrate his fantasy.
Some of us live in the real world not a fantasy world.
