I'm a little surprised, I thought it would be just the opposite based on earlier answers. I am guessing that while there are quite a few here with pensions and/or retiree health care, most have considerable private holdings as well.
I am in this camp.
Because traditional pensions are usually not transferable I realized at age 37 when I started work for my 4th company that I was also started anew on my 4th pension scheme and that I would probably be leaving that company as well before I retired so then began working on Plan B, and started to save for retirement rather than rely on a company pension. Of course, 18 years later and I'm still with the company so I am very fortunate indeed.
