A L Williams popularized the concept of "Buy Term and Invest the Difference" in the 1970's. When market returns are looking good this concept seems to make a come-back even though it's flawed with big assumptions.

You want guarantees? Then you want to build a strong financial foundation with guarantees before you invest. Investing isn't bad, but don't throw away guarantees for speculative possibilities.
