Interesting read, but misleading title. I'd title it:
Many Americans are spending an incorrect amount in Retirement.
They said that the bottom 40% are spending too much...so almost half. Can't accuse them of hoarding:)
They said that the medium person is spending 8% too little. Well, first off, that's 8% is pretty close to correct, and if you are a medium net worth then erring slightly on the side of caution is probably smart if you are going to lean one way or the other, so the medium person is probably doing the right thing.
It's really just the top quintile that's underspending. And even then, many of them probably just aren't trying to maximize for dollars spent, but happiness. I mean, this survey would characterize MMM in the top quintile but underspending category, but he seems like a happy enough fellow. So, I'd title this article:
"Some of the Top Quintile of Americans are Hoarding Cash in Retirement"
...I probably wouldn't make a very good title picker-outer
