Integral part of wealth transfer, estate structures and the ultimate accumulation of generational wealth. Whole life gets a bad rep because of the historically poor growth they offer, but when you look to shield a lot of liquidity from estate taxes, taxes in general, etc. it's the best way to go.
Term is good, but only when used properly. There are plenty of great products that people can buy in their 20's and 30's that offer permanent solutions and are best paired w/ term to cover a certain period when there are kids in the mix, etc.
My firm uses whole life/permanent products all of the time to fund retirement. The death benefit is just that, a death benefit.
