Millions of middle-class Americans face an unexpected reality in today's era of economic growth: their paychecks vary so much that paying bills and saving for the future is exhausting and challenging month after month. This week on Benchmark, Dan and Scott speak with Jonathan Morduch and Rachel Schneider, whose book, "The Financial Diaries," vividly illustrates the financial struggles of more than 200 U.S. families.See omnystudio.com/listener for privacy information.

What on earth is going on in Brazil? Less than a year after impeaching one president for fiddling fiscal accounts, her successor is on the ropes amid allegations of graft. Dig a little deeper and the real problem is a recession deeper than any the country has ever experienced. With Brazil one of the world's 10 largest economies -- and Latin America's largest -- it matters beyond the nation's borders. Sao Paulo native Vivianne Rodrigues, who runs Latin American political news at Bloomberg, joins Dan and Scott to explain what gives. We also hear that the gas station in Brasilia at the center of the scandal doesn't actually have a car wash!See omnystudio.com/listener for privacy information.

Donald Trump's road to 3 percent growth might run through New Zealand. The faraway nation is the only developed economy that's been expanding at such a torrid pace, thanks to the one factor that Trump railed against on the campaign trail: immigration. How did the land of "Lord of the Rings" become such a desired destination, and how are all those people squeezing into such a small country? Joining Dan and Scott is Tracy Withers, who has spent almost two decades covering the economy of his native land as a Bloomberg reporter in Wellington.See omnystudio.com/listener for privacy information.

A major puzzle in the U.S. economy is why wage gains have been relatively subdued in the last couple of years, even as all signs point to a tight job market where employers are having trouble filling positions. One reason is that labor unions just don't have the clout they used to in America. While there are occasional victories, the situation is a far cry from the glory days of the 1970s, and it's also helping reshape the political landscape. Jared Bernstein, former chief economist to Vice President Joe Biden and an expert on labor economics, joins Scott and guest co-host Patricia Laya to explain.See omnystudio.com/listener for privacy information.

The world's easiest place to do business, the second-largest container port and the biggest center for commodities trading. There's a lot more to Singapore than a ban on chewing gum, which is mostly honored in the breach. Smaller than Rhode Island, settlements around modern-day Singapore rose and fell centuries ago on the China maritime trade. Think of it as an Oceanic version of the Silk Road. And as China's economic power expands, the little entrepot is well positioned to keep rising. John Curtis Perry, author of "Singapore: Unlikely Power" tells all to Dan and Scott.See omnystudio.com/listener for privacy information.

Israel's economy is so innovative that it's forcing otherwise hostile Arab neighbors to look at ways they could also benefit -- and the result could eventually be a gradual normalization of relations, if all continues to go smoothly. One example: trade and collaboration in technology and intelligence are flourishing below the radar between Israel and a host of Arab states. Sure, there are a lot of caveats, and whether this will affect relations with Palestinians or Iran is another question, but just the fact that Israelis and Saudis are quietly getting along in one way is a start. Jonathan Ferziger, a reporter for Bloomberg in Tel Aviv, joins Dan and Scott to tell the story.See omnystudio.com/listener for privacy information.

Here's an economic statistic you don't see very often: Top-flight surfing breaks can drive growth. Fresh from his 11-year-old daughter's surfing lesson just outside Sydney, Mike Heath asks guest Sam Wills to run through experiments that he says confirm the theory, especially during El Niño years. Stay tuned as Dan pines for the apartment he left behind in Bondi Beach two decades ago.See omnystudio.com/listener for privacy information.

G, a D and a P. Three letters, lots of trouble. Gross Domestic Product is the world's most common way to measure the value of all goods and services produced in an economy. But does it really deserve its pedestal? Lorenzo Fioramonti, a professor at the University of Pretoria, tells Dan and Scott that the acronym should actually stand for "Gross Dumb Product." He argues that it's responsible for all manner of sins, ranging from the pillaging of a South Pacific island to an instrument used by austerity-craven northern Europeans to hammer Greece. Time for a revolution, Fioramonti insists. Just make sure investors don't crucify you.See omnystudio.com/listener for privacy information.

President Donald Trump spent plenty of time on the campaign trail accusing China of stealing American jobs by taking away factories and using unfair trade practices. But China is actually giving a lifeline in one hard-hit part of the Rust Belt. That makes things between the two nations more complicated than Trump might want to admit as he meets with Chinese President Xi Jinping for the first time. Michael Davis, economic development director for Moraine, Ohio, and Case Western Reserve University professor Susan Helper explain the story to Scott Lanman and guest host Andrew Mayeda.See omnystudio.com/listener for privacy information.

We usually don't think about economics as a life-or-death subject. But for white Americans without a college degree, there's no other way to describe it. With job opportunities limited and an opioid epidemic in full throttle, death rates among this group are skyrocketing, an issue that probably helped elect Donald Trump as president. Anne Case and Angus Deaton, the married academic couple who brought this issue to the forefront, have just issued a followup paper to their groundbreaking 2015 study on the subject. Case returns to Benchmark to discuss the latest findings with Dan and Scott -- and offers her ominous take on what it portends for the future of the nation.See omnystudio.com/listener for privacy information.
