First of all, life insurance is not an investment vehicle. As to whether you now need permanent insurance depends on what you are calling wealthy and the tax situation where you live.I was born in 1980 so, I am almost a Millenial. Since I didn't have any dependents when I was in my 20's, I instead invested intelligently in stocks, real estate, and business ventures. Yeah, they didn't go up in a straight line like life insurance would have (there were a few dips) but I made far more money with far less money than anyone could have with life insurance products. I have done well enough, that I mostly retired at 37. If I die today, my beneficiaries will be quite wealthy.
Now I am prepared to hear the commission life insurance salespeople tell me why I should have bought their products.
