The paper, by William Emmons, Bryan Noeth and Ray Boshara, draws on surveys of 40,000 families that the Fed carried out between 1989 and 2013 to examine the all-important role that your age plays in how much income you make and how much wealth you accumulate. It offers a few clues as to how young people can game the system and end up like their wealthy older counterparts, as well as a lot of evidence to show that things are just different for young people today.
One of the most important points that the paper makes is that everyone's income and wealth tend to follow a kind of natural pattern during their life.
Young people (generally defined here as those under 40) haven't been working for many years, so they don't have an opportunity to save as much; they also need to make investments in things like education and new-home ownership. Middle-aged people (40-61) have been working long enough that they start to accumulate wealth rapidly. And old people (62 and up) begin to draw down on their wealth, to finance their retirement.
From bad to worse
Basically, young people have always been poor. But looking beyond that trend, you can see that today's young people are poorer than young people of the past.
The period of time in which someone is born can also have a dramatic effect on their wealth compared with other generations. The winners of this historical jackpot appear to be those who were born between 1930 and 1945 and came of age after World War II, who are sometimes called The Silent Generation.
Both the Silent Generation and the generation that came before them, called The Greatest Generation because they fought in World War II, benefited from America's rapid economic growth after World War II.
But The Silent Generation appears to get an additional boost because they were born during the Great Depression, a time when people had fewer babies overall. Their lower population meant that they had less competition overall for jobs, housing, investments and other opportunities.
'Lucky few'
Sociologist Elwood Carlson called the generation "the lucky few" because they were smaller than the generation that came before. African-Americans and women born in those years had far more opportunity, and the generation also benefited from the expansion of the American safety net, including Social Security and Medicare, during their lives.
"[P]eople born in the first half of the 20th century simply may have been in the right place at the right time as they were lifted by a rising tide," the economists write.
Then came the Baby Boomers, the populous generation born after World War II. They haven't fared as well as their predecessors, in part because their greater numbers have meant more competition, and perhaps in part because the world is just a different place.
The boomers were the first generation to really experience the effects of globalisation and competition from workers in the developing world. That, as well as automation and the decline of labour unions, have all eroded wage growth on the lower end of the income spectrum.
But even boomers appear to be doing quite well when compared to the generations that came after them. The really sad story is Generation X, which has benefited much less from rising living standards, the St. Louis Fed economists say. Millennials also appear to be faring poorly, though they haven't really been earning income long enough to make historical comparisons.
Growing wider
In just 25 years, the wealth gap between young and old people has yawned wider. In 1989, old families had 7.6 times as much median wealth as young families. By 2013, it had grown to 14.7 times.
According to the economists' calculations, someone born in 1970 has a quarter less income and 40 per cent less wealth than an identical person born in 1940.
It's not clear exactly why this is, the economists say. The financial crisis and Great Recession certainly set young people back, but young people were doing comparatively worse even before that. And the trends are true even though America's younger generations are its most educated ever.
Part of the reason could be that younger Americans are far more diverse than older generations, and race- and ethnicity-based disadvantages continue to loom large in the US, the economists say. White and Asian families are far wealthier than black and Hispanic families in the US, across all age groups.
The difference may also be due to the difference in financial decisions between young and old people. Old people generally have more diverse investments, carry less debt and are more cushioned against financial shocks than younger people.
If young people want to increase their chances of being wealthy, one strategy is to emulate the behaviour of older people: keeping an emergency fund, paying down debt, avoiding high-cost credit, and putting money into higher-returning investments, the economists say.
One strategy that might work for young people is delaying the purchase of a house. By doing so, young people can save and make a bigger down payment later, and thus lower their debt burden, as well as make more diverse investments in the interim.
But even if Millennials and Gen Xers follow these strategies, the historical trends don't appear to be on their side. "Some people are just born lucky," the economists conclude.
