Not far from the hotels that host parties, and the neighborhoods where the booze flows, Kasim Ali sells fruit. He hasn't always, but he can't find another job. "I make 200 rupees a day," he said. "But my bills are more than 150 rupees per day," meaning he puts less than a dollar into his pocket at the end of each day.
"I am," he said, "depressed. I was only educated up until grade 10. I don't have a job. I can't afford anything. The prices have risen too fast."
Over the last year the price of clothes rose 9 percent and the price of food jumped 12 percent. The cost of flour rose more than 20 percent from November to December, and severe shortages created lines long enough that soldiers were called on to protect what little grain there was.
Abdur Rehman works in a Karachi market repairing stereos -- which means he doesn't have much business these days. "The situation is very bad in Karachi. Flour is too expensive. And there are no jobs. There is no business. Everything is too expensive. And we are too worried," he said.
Asked what he wants the government to do, he points to the nearly 60 suicide bombings last year -- up from six in 2006. "Please stop the bomb blasts. People are too worried. In the hospitals, in the schools, in the shops -- there are bomb blasts everywhere. We are too worried."
Everyone is afraid of bombs. And those who choose to party are afraid of judgment. This is still a conservative, Muslim country.
"I can order a drink anywhere in the world," Zafar said. "But here, there is still a taboo. We know that what we're doing, we're doing behind closed doors."
Officially there are no bars, no clubs that serve alcohol, and no public use of the ubiquitous hashish that literally grows on the side of some roads. That's not a bad thing, Karachites said. People here respect their religion and almost universally don't mind that alcohol is officially illegal.
But despite the laws of the land, the young elite here are not shy about their taste for a little pleasure. "There's all sorts of substances: alcohol, ecstasy, hash, coke sometimes -- if you're lucky," Butt said with a laugh. "Anything. Everything. Everything happens here."
"Recently, there has been a lot of imported cocaine," Javaid said. "Richer people are more into it. … The ones who have access to it wish to make use of it, and if they do, they get used to it, and you know how it goes."
But that isn't to say that for the young elite, life is one big party. A few hours before she attended a recent event, Sanai had to leave work early. Gunfights had broken out in the city after a rumor spread that a local politician had been shot to death.
The rumors were untrue, and the politician had to appear on television to stop the violence.
In Karachi, it always feels as if violence is simmering just below the surface.
It exploded on Dec.27, the night Benazir Bhutto was killed. Across the country mobs burned down stores, set fire to cars and caused millions of dollars in damage. Sanai, the manager of programming at the radio station City FM 89, was on the air that night. She played "The Blues Are Still Blue" by Belle and Sebastian. She played "Don't Stop the Music" by Rihanna.
When she discovered that her uncle was hiding in his shop, lights off and shutters closed, hoping the looters would ignore him, she frantically left to pick him up. "Anything that stops us," she said to her driver, "you just run it over. I don't care."
