It wasn’t long ago that Havana’s Plaza of the Revolution was packed with American tourists knocking into each other with selfie sticks while taking photos of the iconic image of the revolutionary Che Guevara and trying to catch a ride in a candy-apple red 1952 Chevrolet Bel-Air.

Today, those polished 1950s-era American convertibles that came to symbolize quintessential Cuba sit empty, the tourists they once carried largely gone.

The drivers spend their lives like most Cubans do: coping with prolonged power outages, standing in line at poorly stocked supermarkets and watching their friends, family and neighbors — sick of all the hardships — pack up and leave.

Ten years ago, President Barack Obama stunned the world by restoring diplomatic relations with Cuba, ending more than 50 years of Cold War estrangement between the United States and a country with which it had once been on the brink of nuclear war.

For two and a half years, Cuba brimmed with enthusiasm amid a remarkable wave of investment and tourism, fueled by deals signed by major American companies such as Google, AT&T and Major League Baseball.

But a financial implosion caused by a cascade of factors — the tightening of U.S. policy by the Trump administration, Cuba’s mismanagement of its economy, the crushing effect of the Covid-19 pandemic — has kept visitors away and launched an immigration exodus of epic proportions.
