4. The Economic Catch-22

Even if these countries could physically run their matters, their economies would shrink significantly.

• Foreigners are not just workers; they are consumers.

• Removing them would mean a catastrophic drop in real estate value, retail spending, and tax revenue (VAT). The entire "service economy" model these countries have built would evaporate.

Summary Table: Reliance Levels

The short answer is: No, not currently. Here is a breakdown of why, and how they are trying to fix it.

1. The Sector "Deadlock"

In most of these countries, there is a sharp divide between where citizens work and where expats work.

• The Private Sector: In countries like the UAE and Kuwait, expats make up over 90% of the private-sector workforce. This includes everything from the CEOs of multinational banks to the technicians maintaining the power grid.

• Manual Labor & Infrastructure: Construction, waste management, and heavy industry are almost 100% expatriate-run. Without foreign labor, the physical upkeep of these desert cities—water desalination, electricity, and sanitation—would stop.

• Essential Services: While the police and military are mostly staffed by nationals, the healthcare systems (doctors and nurses) and education sectors are heavily reliant on foreign talent from India, Egypt, the Philippines, and the West.

2. The Saudi Exception (Vision 2030)

Saudi Arabia is the only country in this group with a large enough citizen population (~21 million) to theoretically run itself.

• They have launched "Saudization" programs that mandate hiring locals in retail, HR, and mid-management. 

• The Reality: Even with 21 million citizens, the Kingdom still lacks enough trained specialists for its "Giga-projects" (like NEOM) and still relies on expats for nearly half its total workforce.

3. The "Sovereign Capability" Gap

By 2026, the challenge has shifted from "generic labor" to "high-tech sovereignty."

• Technology & AI: The GCC is racing to become a global hub for AI and data. Currently, they "import" this expertise. If they lost foreign nationals today, their digital infrastructure and banking systems would likely fail within weeks due to a lack of specialized local engineers. 

• The Goal: Governments are pouring billions into local universities to ensure that by 2035–2040, the "brain" of the country (decision-making and tech) is national, even if the "hands" (labor) remain international.
