Others math, may vary of course. But in our case we will receive about 70k per year in Medicare, and social security benefits. (50K plus per year SS, and Medicare about 20k per year cheaper, than if we had to buy private insurance with the same benefits.
If we were to buy, a life time annuity, with a cola, that type of annuity would be about a mil and a half. To get that kind of return
We were pretty good savers, and have money in the bank. But I wonder, if we would have had the will power to save an additional 1.5 mil. Short answer I doubt it. And I think that would apply to most Americans.
I paid max social security and Medicare, for most of our 40 years in business, But I very much doubt, the total is more than 700k.
The other thing not mentioned is wealth transfer. How many of us had parents, that because of SS and Medicare, were able to stay in their own homes? Which when they passed us kids sold and made quite a profit. And they did not end up living with us for years.
So I don't know, I just think there are a lot of different ways to look at this
