One of the biggest factors in figuring out when early retirement is possible for me is the uncertainty of health care. I've looked into ACA plans, tried to estimate how much things will cost when life is healthy and when it isn't, and considered alternative scenarios, but haven't made myself comfortable, yet, with my options. What are you considering before you qualify for Medicare?

• ACA and other commercial plans?
• Spouse/partner not retiring early?
• Participate in a country with universal/national healthcare?

Edits: This is a distraction from the world crumbling near me.

I just want to talk equations as those are distracting.

Original: I have been thinking of Generational Wealth lately, and my thinking is ~~unrefined~~ muddy. I wish to get feedback and your thoughts.

Before I learned of FIRE, I had assumed Generation Wealth required a wildly high sum of money (hundreds of millions of USD). Anything less was just a nice retirement. (I had also assumed retiring was simply impossible.)

Like with many things about compounding, it matters critically to not spend all of one's money and to have time. Too little money or too little times and money goes to zero. Even a little more than the "balance" point, and the number go to infinity.

At 2 children per household, the number of households being supported grows at a larger rate than reasonable investment gains. The tripling time at 4% real gain is 28.01 years. (The tripling time for supported households is shorter than this. Tripling time chosen as the initial household will then become 3. Though in my scenario below the number of households in each 28 year period only doubles.)

If each new generation are comprised of twins, starts to receive on their 28th birthday, and sadly this is the day their grandparents die, then the balance seems to work out if the initial parents overshoot their FI number by about 66% either by over-saving or not withdrawing for years.

(Generational Wealth depends heavily upon how many children each generation produces. One under earner/over producer of children will sink the whole thing... )

It would seem the best I can hope to do is to give my children and grandchildren an education and a head start. They will have to live their own lives and make their own contributions to their retirements.
