"Don't reinvent the wheel" is a common phrase, but structural engineer Roma Agrawal doesn't buy it. 

Roma has a new book out, Nuts and Bolts: Seven Small Inventions That Changed the World (in a Big Way). And in it, she argues that the re-interpretation of the wheel has been critical to modernizing the economy from a pottery wheel in ancient Mesopotamia to the gyroscope on the International Space Station. 

Today, how this constant reinvention fuels economic progress.

According to a government report released this week, Congress has until 2033 to fix Social Security before retirees receive an automatic benefit cut of about 21%. This is a more optimistic estimate from a previous report that stated the Social Security Trust Fund would run dry sooner, but it still paints a grim picture for a program that millions of retirees rely on.

Today, NPR's Chief Economics Correspondent joins the show to explain what exactly lawmakers can do to fix Social Security and why proposed solutions might be easier said than done.

We ask Gabriela and two other Venezuelans: what are economic conditions like at the moment? How has life changed since the pandemic? Some of the answers surprised us.
