My scenario focuses solely on interest income for simplicity’s sake. There are other investments one can make to increase your gain, but such investments are more volatile. You could end up doing quite well and increasing your nut, or you could invest in the wrong stock and lose a large chunk of it.

I also left our other considerations for simplicity’s sake like the fact that most retirees are couples and past the age of 65 the odds that one of you will require significant medical treatment increases every year. Some elderly couples are getting divorced so as to only bankrupt one of them when this happens.

Life is messy and $1M will only work in the best case scenario. It’s just not realistic. By allowing people to think that $1M is enough, you’re actually leading them into ruin. We need to be aware that retirement is becoming a dicey proposition and we should be taking steps to ensure that the elderly will be provided for in the coming decades, especially since a large number of millennials won’t have children to make sure they are properly cared for.
