Nope. Didn't just surf in. I was responding to your specific post about a specific video.Apparently, you just surfed in and are unaware of the other videos that I and others have linked from Sean.
I have no idea what he says in his book or anywhere else, and it had nothing to do with your post and the video you posted.He covers the 'to Roth or not' in other videos and if that's not enough covers it very, very specifically in his excellent book. However, the tax calculations in all his videos are quite helpful as they carry through to all proper analysis. And when things aren't 'no-brainers, ' proper calculations and their application are crucial.
You think he did "all the proper analysis" in that video because he concluded that a woman with over $300k per year would be "fine" and would pay taxes ($79k at about 25% effective rate) that he concluded were good. I disagree. I don't think he did ALL the proper analysis because most people with over $5 million dollars aren't worried about whether they will be fine or if they can manage to live on over $300k per year (though some of them might be a bit surprised to learn that they are paying $79k in taxes for the first time).
I think "all the proper analysis" would have included what would have happened if they had started planning and converting when they were younger and comparing it to the scenario the widow ended up in. Of course, a variety of factors would need to be discussed for a proper analysis, but he didn't even attempt it.
