<prompt> Human: My dad recently read this book and was saying it has some really helpful information regarding retirement planning. A big thing he noted was the variation in income tax over the past 100 years and how it is expected to increase - and how to best plan for retirement with this in mind. Anyways, just curious if anyone has read it their thoughts should I buy it off Amazon for 15.  <response>: Ive read it and you wont take away much from it. It follows some of the basic retirement tactics and then veers way off path suggesting you invest in a Life Insurance Retirement Policy. After that part it got sort of scammy salesman-y with a case study and lots of assumptions.Id feel a lot more comfortable following a Roth Conversion Ladder.
