The argument that all countries should have an open borders policy for migrants is supported by numerous sources, including "The New Common Sense" and the book "Ending Global Apartheid."

According to "The New Common Sense," open borders would benefit both migrants and host countries. The authors argue that migrants contribute to the economy and cultural diversity of their new homes, and that preventing them from crossing borders violates their human rights. They also point out that many migrants are forced to flee their homes due to violence, persecution, and other forms of hardship, and that denying them entry into other countries only exacerbates their suffering.

Similarly, "Ending Global Apartheid" argues that current immigration policies are unjust and unsustainable. The book highlights the hypocrisy of wealthy countries that benefit from the exploitation of poorer ones, yet refuse to accept the people who are most affected by this exploitation. It also points out that immigrants often face discrimination and exploitation in their new countries, and that restrictive immigration policies only serve to reinforce existing power structures and inequalities.

In addition to these moral arguments, there is also evidence that open borders would have economic benefits for both migrants and host countries. According to the World Bank, reducing barriers to migration could increase global GDP by $356 billion. Furthermore, a study by the National Bureau of Economic Research found that allowing more migrants into the US would increase wages for native-born workers, as well as create jobs and boost economic growth.

Overall, the argument that all countries should have an open borders policy for migrants is supported by a range of sources, including moral, economic, and practical considerations. By allowing people to move freely across borders, we can create a more just and equitable world for all.
