This collapsing socialist state is suffering one of the most dramatic outflows of human talent in modern history, with Aquiles Nazoa offering a glimpse into what happens when a nation begins to empty out. Vast gaps in Venezuela's labor market are causing a breakdown in daily life, and robbing this nation of its future. The exodus is broad and deep - an outflow of doctors, engineers, oil workers, bus drivers and electricians.
So far this year, 48,000 teachers - or 12 percent of all staff at elementary and high schools nationwide - have quit, according to Se Educa, an educational group. The vast majority, according to the group, have joined a stampede of Venezuelans leaving the country to escape food lines and empty grocery store shelves.
Esperanza Longhi - who also taught second grade - quit in February. She's at home, packing for Peru. To get there, she'll go through Ecuador - the same country where Maryoli Rueda, who used to teach third grade, recently moved.
Principal Deliana Flores has tried and failed to find qualified replacements. As droves of teachers leave, some grades in Venezuelan schools have gone months without classes. At Aquiles Nazoa, the third grade stayed home for two weeks. Desperate, Flores is plugging holes with unpaid volunteers - basically school moms such as Kory Hernandez, 24.
But it isn't really working.
Hernandez dragged the 9-year old back into the classroom by his shirt sleeve, then sunk into her seat and sighed.
"Quiet," she said helplessly, as her class erupted in open rebellion.
"Please," she said. "How are you ever going to learn?"
Think of Venezuela like one big factory where the societal assembly line no longer works - partly because there are fewer and fewer people to run it.
The Venezuelans are running from a nation broken by failed socialist policies, mismanagement, corruption and lower global oil prices - the country's principal source of cash.
"It's not just about a few doctors leaving anymore," said Tomas Paez, a migration expert at the Central University of Venezuela. "It's about (understaffed) hospitals closing down whole floors."
Tens of thousands of Venezuelans - especially from the upper classes - began leaving the country following the rise of left-wing firebrand Hugo Chavez, who became president in 1999. But in the past year, Venezuela's economy has fallen off a cliff, prompting a more drastic exodus. Experts say the outflow is set to surge in the aftermath of the re-election of President Nicolas Maduro on May 20. Denounced internationally as illegitimate, the election removed any real chance for change. Amid food shortages, hunger is pervasive and growing in a country that was once Latin America's richest per capita. Without medicines, treatable diseases such as HIV and malaria have become rampant. With hyperinflation soaring toward 14,000 percent, it now takes five days work at the minimum wage to buy a dozen eggs.
The value of local salaries is falling by the day. In the middle of 2017, an average teacher's salary was worth nearly $45.
Today, it's worth about $8.
"If we continue like this, Venezuela won't even be a Third World country anymore," said Flores, the school principal.
"There's a huge lack of people in operations and maintenance now," said Ricardo Sansone, head of Familia Metro. "They have no people to sell tickets at many stations, so passengers are often not even paying to use the subway."
At the Jose Manuel de los Rios Children's Hospital in Caracas, 68 doctors - or 20 percent of the medical staff - quit and left the country over the past two years. The hospital's cardiology department is now only open for a morning shift, since three of its six specialists are gone. There are 300 vacant nursing positions. Personnel shortages are so bad that the facility can only staff two of its seven operating rooms.
"It now takes eight months to a year for a surgery appointment," said Huniades Urbina, a senior staff pediatrician.
"Every day, we're receiving dozens of calls from colleagues saying they're going to Colombia, Peru and Ecuador," Torres said. "They're being replaced by people who are mostly not qualified."
Seven miles down the road from Aquiles Nazoa Elementary School, the campus of Simon Bolivar University is oddly quiet. Once considered the MIT of Venezuela, a university that churned out some of the best Latin American engineers and physicists is now in danger of becoming a ghost town.
Thirty professors retired last year but have not been replaced, in part because of a lack of qualified candidates. The university is so short-staffed that three departments - languages, philosophy and electronic engineering - are about to close.
Yet as Venezuela's young people depart in droves, Simon Bolivar also does not have the demand it once did. Three years ago, electronic engineering had nearly 700 students. Now, it's down to 196.
Jesus Perez, 20, is one of the students who are just giving up. He was studying to be a computer engineer. But over the past six months, he's lost 10 pounds from a lack of food. "I can't wait anymore," he said. "I have to leave. So far, 15 of my friends from school have left the country since February."
He'll go to Peru, a country that two decades ago was far poorer than Venezuela.
What will he do?
"I don't care," he said. "Be a waiter, clean floors. I can't ask for much."
A 40-minute bus ride away from Aquiles Nazoa Elementary School, Deiriana Hernandez sat on the floor of her one-room home, puzzling out her homework.
A student at the school, she is on her third teacher in one year. One of them retired. Another quit to leave the country. Her latest - "Mrs. Kory" - is a volunteer who only recently finished her high school equivalency degree.
Deiriana recently spent two weeks at home because her school could find no one to teach third grade. With a volunteer teacher, she can at least go to class. But she and other students are slipping behind.
Their grades are falling, and behavioral problems are worsening. Deiriana is 9. But she can barely read.
She was looking at a list of 16 words now, and instructions to separate them into four groups - animals, colors, cities, plants.
She scratched her head and called for her mother.
"You don't understand?" said her mom, Yanelis Blanco, 26.
Blanco was nervous.
"She's behind for a third grader," the mother said. "She doesn't read correctly, has lots of grammatical errors when she writes. It's a terrible thing that her teachers constantly leave."
Deiriana's classmates are also leaving. Last year, her class had 24 students. Now they're down to 19.
Two days after Deiriana labored over her homework, her mother received news from the school.
Mrs. Kory had quit.
For Deiriana, it's back to staying at home, where her family is discussing another big change. Unable to put enough food on the table, her father is thinking of going to Peru to look for work.
"At least maybe that way we can pay for private schools where teachers, I imagine, are being paid better and given incentives to stay?" Blanco said. "I don't know."
