HAVANA — On weekend nights in Havana, young hipsters fill the sidewalks at a busy intersection near the seafront and spill into the park below, passing rum bottles between them, smoking cigarettes and playing guitars.

Black t-shirts, low-slung jeans, oddball haircuts and tattoos are in vogue at this spot, a favorite hangout for Cuban youth with a counter-cultural, slightly rebellious feel to it.

On one corner, police question a few overzealous partiers, but generally leave people alone compared to years past, when, according to one regular, Ernesto Ramis, they made everyone move along.

Ramis, 25, says you can get drugs here, but there is no overt evidence of illegality this night only a sense that being young in Cuba today is different, that conformity to the old ways has faded.

"The main difference," says Ramis, pointing toward the Straits of Florida, barely visible in the darkness, "is that everyone wants to leave."

His use of the word "everyone" is an overstatement, but he has touched on one of the Cuban government's biggest problems — youthful discontent with a system many view as lacking opportunity for a better life.

It is not a problem unique to the Caribbean island, which like many underdeveloped countries struggles to hold on to its best and brightest, but unlike most others faces the added difficulty of doing so at the doorstep of a hostile superpower with an open door immigration policy for Cubans.

The government, well aware of its youth problem, is gradually changing the Soviet-style, state-run economic model put in place after the 1959 revolution, partly to address the issue.

There are young people taking advantage of the reforms by opening their own businesses or going into jobs in the island's growing private sector, but there are others who doubt the government will move fast enough to make a difference, and they want out.

Most hope to go to the United States, only 90 miles away, following in the footsteps of an estimated 1.5 million who have preceded them since the revolution.

Other countries such as Canada and Spain are also sought-after destinations, although Spain's economic woes have lately made it less attractive.

Some Cubans claim that when the sky is very clear you can see the glow of lights from Florida in the night sky, which is doubtful, but an indication of the psychological proximity of the two places despite years of official hostility.

The U.S. approves 25,000 to 30,000 immigrant visas for Cubans each year, and several thousand more enter the country without visas from third countries or by sea.

An elderly Communist Party member said the difference from the past is that the desire to leave is so widespread among the young.

"Unfortunately, if you talk to 10 young people today, nine of them will tell you they want to leave Cuba. They don't see a future," she said, not wanting to be identified.

Ulisses Guilarte, head of the party in Artemisa province and a member of the Central Committee, told Reuters the reason for youthful disillusionment was obvious.

"It is clear the economic situation is difficult, undoubtedly. The young people view their aspirations as still distant," he said.

 LOW SALARIES

The government prides itself on providing free health care and education to its people, but in an economy handicapped by inefficiency and a longstanding U.S. trade embargo, monthly salaries average the equivalent of $20 a month.

Young people have watched their parents scrape by for years and do not want the same fate of little money and limited choices.

They want better-paying jobs, their own homes and cars, access to the Internet and a brighter future. Few have traveled abroad, so they want to see the wider world and live a life they get glimpses of in movies or from tourists or visiting relatives.

Some want to have children, but feel it makes no sense if they have no money and have to share homes with relatives, as many do in Cuba.

"After I graduated and began to work, I realized that with the money I was earning it wasn't enough to have or maintain a family," said computer programmer Estela Izquierdo, 29, before she moved to Montreal with her husband.

It was not an easy decision to leave her family and the life she had known, but time was of the essence.

"I can't wait my whole life (for things to change). I have a biological clock, I have to have kids," she said.

A photograph of the couple posted on the Internet showed them bundled against the Canadian cold, playing in the first snow they had ever seen.

Edgar Saucedo, a musician, said he also wants to have a family, but in the United States, not in Cuba where he shares a Havana home with seven other people.

"It's just not feasible here," he said. "Here you work and you work and at the end of the month you've got 12 CUCs, if you're lucky. What can you do with 12 CUCs?" he added, referring to Cuba's hard currency, valued at parity with the U.S. dollar. Most people earn Cuban pesos, which are 24 to 1 with the dollar.

Saucedo's hopes of going to the United States are based on a vague plan of getting invited up to play Cuban music and, once there, never leaving.

He is a keyboard player by profession, but a friend in the United States making $18 an hour as a garbage pickup man says he can get him the same job, which sounds good to him.

"I'll do whatever work I have to do," said the bearded 33-year-old. "I don't want that much, I just want to have a normal life."

Cuba's outward tide looks unlikely to end any time soon, and may increase.

The government relaxed laws in January, making it easier for Cubans to leave the country, which U.S. officials in Havana say has led to a 10 percent increase in inquiries about visas.

Before the change, most visa applications came from the elderly but now most are coming from young people, they said.

Schools in Havana offering classes in foreign languages, particularly English and French, are overloaded with young applicants.

One woman said she began French classes three years ago with 34 other students, all of whom wanted to learn the language to help them get an immigrant visa to French-speaking Quebec. All but four are now in Canada or have visas to go, she said.

 BRAIN DRAIN

"One of the things that's ironic is Cuba has an educated population, but it doesn't have anything for them to do. They've almost prepared their professionals to emigrate," said Cuba expert Ted Henken at Baruch College in New York.

"I think in some ways the Cuban revolution is the best thing that ever happened to Miami, because half of their professional force was probably trained there," he said.

In a world where population growth is exploding and a region where countries have high birth rates and low median ages, Cuba's population is declining and getting older.

Preliminary figures from a national census last year showed that the number of Cubans had slightly declined from 2002 to about 11 million people.

The median age of Cubans has risen to about 39 from 36 in the 2002 census, according to a U.S. government estimate, far above that of any other country in Latin America.

Under President Raul Castro, Cuba has launched economic reforms aimed in part at providing new opportunities it hopes will be attractive to the young.

In today's placid Cuba, the notion of a youth revolt seems far-fetched, but this government was put in place by young rebels led by Fidel Castro, so it knows the potential of restive youth.
