# The Vertical Class System: Height as Hierarchy

## Overview

GLMZ's social hierarchy is literally vertical. The higher you live, the more you earn, the more you know, and the more the city's systems work in your favor. This isn't metaphor — it's architecture. The Gulch sits at the bottom, the Shelf above it, the Grind alongside, the arcology residential levels above that, and the executive penthouses and Cap access at the top. Social mobility in GLMZ is expressed as physical elevation, and the city's infrastructure reinforces the metaphor at every level.

## The Layers

### The Gulch (Below Sea Level to Ground)
Population: 18,000. Income: Below UBC to Φ200/month. Access: Tier 0. Air quality: Marginal. Natural light: None. Security: Community self-policing. The Gulch is where the city's forgotten live — below the infrastructure, below the attention of the corponations, below the dignity threshold that the rest of the city maintains.

### The Shelf (Ground to Level 40)
Population: 3.2 million. Income: Φ120-400/month. Access: Tier 0-1. Air quality: Adequate. Natural light: None. Security: Minimal corporate presence. The Shelf is the city's working poor — surviving on UBC and supplemental labor, living in converted infrastructure, and maintaining a community that the corponations neither support nor suppress.

### The Grind (Ground to Level 20, Industrial Zones)
Population: 400,000 workers (most live in the Shelf). Income: Φ180-800/month. Air quality: Industrial. Natural light: None. Security: Corporate facility security. The Grind is the engine — producing everything the city consumes and employing the labor force that the Shelf houses.

### Arcology Residential (Level 40-200)
Population: 5.8 million. Income: Φ2,000-10,000/month. Access: Tier 2-3. Air quality: Controlled. Natural light: Filtered through arcology walls. Security: Full corporate security coverage. The arcologies house the corporate middle class — the employees whose labor is intellectual rather than physical, whose housing is comfortable rather than improvised, and whose relationship with their employer is defined by the contract trap that makes leaving as costly as staying.

### Executive Levels (Level 200-300)
Population: 200,000. Income: Φ10,000-100,000+/month. Access: Tier 4-5. Air quality: Premium filtered. Natural light: Direct through exterior walls. Security: Personal protection details. The executive levels are where decisions are made — where the view extends to the horizon, where the air smells clean, and where the distance between you and the Gulch is measured in both meters and moral imagination.

### Cap Level Zero (Level 300+)
Population: 200-400. Income: Variable. Access: Variable. Natural light: Full exposure. Security: None. The Cap is the exception to the hierarchy — a wild space above the controlled layers where the normal rules of the vertical class system break down. The Cap's residents are there not because they're wealthy but because they're unwilling to live within the hierarchy at all.

## The Elevator as Equalizer

The Arcade's vertical transit system is the only space in GLMZ where the vertical hierarchy is temporarily suspended. In an elevator, a Gulch salvager and an executive share a box, breathing the same air, traveling the same shaft. The equality is brief and illusory — the elevator doors open and each person steps back into their stratum — but the shared space matters. It's a reminder that the hierarchy is constructed, not natural, and that the same shaft connects the bottom to the top.

## Aspiration and Despair

The vertical class system's most insidious feature is its visibility. A Shelf resident can look up and see the arcologies. They can see where the air is cleaner, the light is brighter, and the walls are smoother. The hierarchy isn't hidden — it's displayed, constantly, as the physical architecture of the space they inhabit. The aspirational interpretation: anyone can rise. The realistic interpretation: the distance between here and there is measured in Φ that you'll never earn, augmentations you'll never afford, and connections you'll never make.
