As it enters its 11th year, America's economic expansion is now the longest on record - a streak that has shrunk unemployment, swelled household wealth, revived the housing market and helped fuel an explosive rise in the stock market.
Yet even after a full decade of uninterrupted economic growth, the richest Americans now hold a greater share of the nation's wealth than they did before the global financial crisis began in 2007. And income growth has been sluggish by historical standards, leaving many Americans feeling stuck in place.
Those trends help explain something unique about this expansion: it's easily the least-celebrated economic recovery in decades.
As public discontent has grown, the issue has become one for political candidates to harness - beginning with US President Donald Trump in 2016. Now, some of the Democrats running to challenge Mr Trump for the presidency have built their campaigns around proposals to tax wealth, raise minimum wages or ease the financial strain of medical care and higher education.
America's financial disparities have widened in large part because the means by which people build wealth have become more exclusive since the Great Recession.
Fewer middle-class Americans own homes. Fewer are invested in the stock market. And home prices have risen far more in wealthier metro areas on the coasts than in more modestly priced cities and rural areas. The result is that affluent homeowners now sit on vast sums of home equity and capital gains, while tens of millions of ordinary households have been left mainly on the sidelines.
"The recovery has been very disappointing from the standpoint of inequality," said Gabriel Zucman, an economist at the University of California, Berkeley, and a leading expert on income and wealth distribution.
Household wealth - the value of homes, stock portfolios and bank accounts, minus mortgage and credit card debt and other loans - jumped 80 per cent in the past decade. More than one-third of that gain - $16.2 trillion (Dh59.5tn) in riches - went to the wealthiest 1 per cent, figures from the Federal Reserve show. Just 25 per cent of it went to middle-to-upper-middle class households. The bottom half of the population gained less than 2 per cent.
Nearly 8 million Americans lost homes in the recession and its aftermath, and the sharp price gains since then have put ownership out of reach for many would-be buyers. For America's middle class, the homeownership rate fell to about 60 per cent in 2016 from around 70 per cent in 2004, before the housing bubble, according to separate Fed data.
The other major engine of household wealth - the stock market - has not benefited many people, either. The longest bull market in US history, which surpassed its own 10-year mark in March, has shot equity prices up more than four-fold. Yet the proportion of middle-income households that own shares has actually declined.
The Fed calculates that about half of middle-income Americans owned shares in 2016, the most recent year for which data is available, down from 56 per cent in 2007. That includes people who hold stocks in retirement accounts.
The decline in stock market participation occurred mainly because more middle-income workers took contract work or other jobs that offered no retirement savings plans, the Fed concluded.
Hannah Moore, now 37, has struggled to save since graduating from college in December 2007, the same month the Great Recession officially began. She has worked nearly continuously since then despite a couple of layoffs.
"I had many jobs, all at the same time," she says. "It's just not been the easiest of decades if you're trying to jump-start a career."
She works for a design firm in Los Angeles that contracts luxury apartment developers to build rental housing marketed to high-tech employees. She loves the work, but struggles with Los Angeles' high costs.
Ms Moore says she could afford a monthly mortgage payment, but she lacks the savings for a down payment. About half her income, she calculates, is eaten up by rent, health insurance and student loan payments of $850 a month.
As financial inequalities have widened over the past decade, racial disparities in wealth have worsened, too. The typical wealth for a white household is $171,000 - nearly 10 times that for African-Americans. That's up from seven times before the housing bubble, and it primarily reflects sharp losses in housing wealth for blacks. The African-American homeownership rate fell to a record low in the first three months of this year.
Most economists argue that higher income growth is needed to make it easier for more Americans to save and build wealth.
Mr Zucman favours a higher minimum wage, cheaper access to college education and more family-friendly policies to enable more parents to work. He and his colleague Emmanuel Saez, also an economist at the University of California, Berkeley, helped formulate senator Elizabeth Warren's proposed wealth tax on fortunes above $50 million to help pay for those proposals.
Income growth has lagged partly because for most of the expansion, employers have had a surfeit of workers to choose among when filling jobs, leaving them little pressure to raise pay.
Not until 2016 did the unemployment rate fall below 5 per cent. Average hourly pay finally began to pick up, with the lowest-income workers receiving the fastest average gains.
"Overall, there's growing inequality," Elise Gould, an economist at the liberal Economic Policy Institute said, "with signs of hope at the bottom. It's just taken a very long time."
