I would say that its a pretty bad article considering that we have a negative savings rate, and that there are very few people who can say that the save enough money. When you throw in inflation, skyrocketing medical costs that the boomers will be facing, further potential increases in oil prices, and a likely recession / stock market and housing collapse, no amount of savings is too much or has ever been.
They found that 88 percent of all households with breadwinners over age 51 had accumulated sufficient resources to finance adequate consumption in retirement. … Probably are considering their home equity as a source of "resources" which is very risky at best.
I also don't see how this can be a bad thing, because whatever these boomers eventually die with, even if it is more than they need, will be passed on to their kin, and will be consumed immediately by the next generation which is much further in debt and has much worse savings habits anyways.
