David Chen had been selling air for seven years. He didn't choose the job. The job chose him, the way a crack in the sidewalk chooses where the weed will grow.

He worked for Sterling & Associates, which was appropriate because Jonathan Sterling owned most of Lower Manhattan and David sold him the smallest possible unit of product: a cubic foot of guaranteed fresh air, packaged in a digital contract that cost more than David's monthly rent.

The顶层 apartments were on the eightieth floor and above. David showed them to clients on Thursdays and Fridays, when the light came through the单向玻璃 at an angle that made the city look like a model you could hold in your hand. The clients were always the same: wealthy, well-dressed, emotionally flat. They didn't fall in love with the apartments. They acquired them, the way you acquire a painting or a car or a piece of land.

"Each unit comes with our Premium Air Package," David said, standing in the center of a living room that was larger than his entire apartment building. "Independent ventilation system. HEPA filtration. Humidity control. The air in these apartments is tested weekly and certified clean by three independent laboratories."

The client nodded. He was looking out the window. Or rather, he was looking through the window, because the glass was单向. He could see the city. The city couldn't see him.

"How much?" he asked.

David gave the number. The client didn't blink. He wrote a number on a card that was handed to him by an assistant who appeared from somewhere and disappeared just as quickly.

David went back to the elevator. He went down eighty floors. He went through the lobby, which was marble and gold and smelled like lilies, and he stepped out onto the street.

The street smelled like exhaust and fried food and the particular brand of desperation that only a city of eight million people can produce. David walked to the subway, took the train to Midtown, and walked to his building.

His building was not new. It was not old. It was the kind of building that existed in the space between, a beige rectangle with a broken intercom and a lobby that was clean enough but not beautiful. His apartment was on the sixth floor. The air in his building was acceptable. Not premium. Not toxic. Acceptable.

He unlocked his door and took off his tie. He stood in the center of his living room and looked at the window. The window looked across at another window, which looked across at another building, which belonged to Sterling. Everything belonged to Sterling, eventually. That was how the city worked. You bought a building. Then you bought the building next to it. Then you bought the block. Then you bought the air rights above the block. Then you bought the building across the street so you could connect them with a skybridge.

David's phone buzzed. A text from Maria Santos in his building: Mr. Chen, can you come to my apartment? The air vent is making a noise.

David put on his shoes. He went to Maria's apartment. He fixed the vent. It was a loose screw. It always was.

Maria was a保洁员. She cleaned the offices in the Sterling tower three days a week. She was forty-two, from Puerto Rico, mother of two. She spoke English with a rhythm that was musical even when the words were simple.

"Thank you, Mr. Chen," she said. "It's been so loud. I can't sleep."

"I tightened the screw. It should be quieter now."

She looked at him with eyes that were tired and grateful and something else that David couldn't name. "Mr. Chen, can I ask you something?"

"Of course."

"Do you think it's fair?"

"What's fair?"

"The air. The buildings. Everything."

David thought about it. He thought about the顶层 apartments on the eightieth floor. He thought about the单向 glass. He thought about his own apartment, with its acceptable air and its window that looked at another window.

"I don't know," he said.

Maria nodded. She didn't press. She had learned, like everyone else in the building, that some questions didn't have answers that helped.

That evening, David went to the roof. The roof of his building was flat and covered in gravel and a HVAC unit that hummed all summer and all winter. He sat on the edge and looked across at the Sterling tower.

From this distance, the tower was a needle of glass and steel, rising out of the city like a monument to something David couldn't name. Not success. Not power. Something more basic than that. The ability to say: this is mine. This is mine. This is mine.

He had seen the inside of those顶层 apartments. He had stood in rooms where the air was so clean it felt like breathing water. He had watched wealthy clients nod at numbers without blinking. He had accepted their cards and walked away and gone back down eighty floors to air that was acceptable but not premium.

He had done this for seven years.

He took out his phone and opened the Sterling & Associates app. He navigated to the air package section. He selected the basic plan. He entered his credit card number. He confirmed the purchase.

One cubic foot of guaranteed fresh air. Monthly delivery. Certified clean.

He had just bought air from himself, in a sense. He had paid Sterling & Associates to sell him air that he helped sell every day. The loop was complete. The circle was closed. The city had eaten him and he had paid for the privilege.

He sat on the roof and watched the lights of the Sterling tower go on, one by one, like stars being born in a private universe.

He didn't feel anger. He didn't feel sadness. He felt nothing, which was perhaps the most honest thing he had felt in years.

Below him, in his apartment, Maria was sleeping with the window open, listening to the vent make its occasional clicking sound, breathing air that was acceptable but not premium, in a city where everything belonged to someone else and nothing belonged to her.

David went back inside. He closed the door. He sat at his table and ate a sandwich and watched the news and went to bed.

Tomorrow he would show more apartments. Tomorrow he would sell more air. Tomorrow he would sit on the roof and watch the lights go on.

This was his life. This was the property he owned. This was the air he breathed.
