Maybe mine is the minority view, but I found it a horrendous waste. When I left the employer it offered to have my portion of the policy transferred to me personally so that I could "continue to enjoy the benefits". I didn't even bother responding (despite leaving on otherwise very good terms).
While I work, I expect to be remunerated. But I don't allow myself the hubris to expect that remuneration should continue in perpetuity. If I decide not to work, or am unable to work, I would prefer to adjust my circumstances to accommodate that fact, rather than continue to pretend otherwise.
