Why don’t the five-eyes nations have this system? Any citizen from GB, CA, USA, NZ & AU is automatically entitled to seek employment in any of the others? Less push & pull factors as a similar standard of living, get all your immigrants from them?

 Certainly!

• The Five Eyes alliance, comprising the United States, United Kingdom, Canada, Australia, and New Zealand, primarily collaborates on intelligence-sharing and security matters. However, the idea of establishing a system where citizens from these nations have automatic employment entitlement in each other's countries faces multifaceted challenges.

• Firstly, while these nations share common values and strong diplomatic ties, they maintain distinct immigration policies and laws. Each country designs its immigration system based on its unique economic needs, social considerations, and national security priorities. Harmonizing these policies across all Five Eyes countries would require extensive negotiations and adjustments to align differing priorities.

• Secondly, allowing unrestricted movement for employment might pose challenges related to labor markets and job availability. While these nations generally share a similar standard of living, discrepancies in employment opportunities and labor demands exist. Creating a seamless employment system could result in imbalances, impacting local job markets and potentially affecting domestic workers.

• Thirdly, there are legal complexities to consider. Immigration laws encompass a broad spectrum of regulations, including visa requirements, work permits, and residency qualifications. Aligning these legal frameworks across different countries with diverse legal traditions, administrative structures, and legislative processes is a daunting task.

• Furthermore, socio-political factors also play a significant role. Public opinion, cultural differences, and societal attitudes toward immigration vary among these nations. Implementing a system that allows free movement for employment might face resistance due to concerns about preserving national identity, protecting local job markets, and managing the integration of newcomers.

• Additionally, issues related to national security and border control cannot be overlooked. Each country has its own security protocols and measures in place to safeguard its borders and citizens. Integrating a unified employment-based immigration system could raise security concerns and necessitate substantial coordination and monitoring mechanisms.

• In conclusion, while the idea of a unified system for employment across the Five Eyes nations seems appealing in theory, in practice, it presents intricate challenges. Harmonizing immigration policies, addressing economic imbalances, navigating legal complexities, considering societal attitudes, and ensuring security measures would require extensive cooperation and compromise among these countries, making it a complex endeavor to implement.
