Your suggested plan sounds good in theory, but is not realistic in todays American job market. Yeah, if you are very persistent they will grant you the entire interview slate, and pretend they have a robust diversity program etc., but in reality their is significant age discrimination especially against older white males > 55. Older women, or those of other races, nationalities etc. all stand a better chance because they help fill the Corporate diversity slate. So, after medical care this is another one of America's big issues/challenges.
I know first hand what
@slipkid is referring to, as I've been there. The only place left for older people is Consulting, if you are fortunate enough to have a niche and find the opportunity. In that realm age, experience, and wisdom are all appreciated and needed.
