This is really odd maybe but I don’t know a single boomer who will not be able to retire.
They will not be spending or living like they are today, but most have their primary paid off and the few who don’t are planning to retire in a lower cost area or even country. (all have worked full time and earned above somewhat above average wages, only a few are in what I would call the rich Category 1-5Million range).
Contrary to what a lot have said, you don’t need to be a millionaire to retire (it helps, but it is not a requirement).
One thing, Having good health is far more important than being a millionaire, being healthy gives you a lot more options.
