The Great Risk Shift by Jacob Hacker presents some interesting data. I don’t always agree with his conclusions but I think the information he presents is interesting.
The most interesting piece of data to me: The chance of a 50% drop in income in 1970 was 7% for any person. By 2002 it had grown to 16%. While this seems to include some questionable “data” such as divorces, retirees… Still the fairly steady climb (see chart page 31) from 1970 to 2002 shows this is one factor that should be a consideration in saving and spending plans. Don’t assume you will earn more and more every year. You will likely have some fairly large drops in income during your lifetime. Plan for it.
Some more interesting data in 1992 7.9% of 25-34 year olds in the USA had debt payments over 40% of their income. In 2001 that rose to 13.3%. In 1984 median wealth for families with a head of household 55-64 was 4 1/2 times as wealth as those of 25-34 year olds, in 2003 it was 13 1/2 times as great. (page 99)
While the average 401(k) balance is $47,000 the median balance is $13,000 (a relatively few large balances skew the average to make it much higher).
Overall I tend to look at the data he presents and think people better consider these realities and plan knowing them. Jacob Hacker seems to more often say that this is unreasonable and show the hardships faced by those that either could not plan better (it was out of there hands which I would agree is part of the problem and requires some public policy changes) or who choose not to (which I would find the case more often than he would). Well worth reading in my opinion.
