Although the approach of income investing is still relegate to a few retirees, I'm wondering how this might change as retirees hit the streets and are told by their well trained TR investment advisors that they are beginning a downward negative savings on their life savings. That is, the quarterly (or annual) account statements will gradually decline....and this is normal and to be expected. Somehow, I imagine this is going to be a tough pill to swallow for new retirees.
One possible solution is life income from insurance products. In fact, I just looked over a URL from 'Benefits Link' with an article (or perhaps a sales brochure) on the use of life annuities for women called 'The Female Factor' at http://www.paycheckforlife.org/uploads/ASR-white_paper_FINAL.pdf . Take a look and see what you think.
But due to the adverse psychology of reverse-savings, we may see more interest in income investing as time moves along.
