Final answer:
Increasing funding or aid to origin countries of immigrants to decrease illegal immigration focuses on Economic development. This approach is part of broader immigration policy reforms that include creating conditions to reduce migration push factors and focus on admitting higher-skilled immigrants.
Step-by-step explanation:
The strategy of increasing funding or providing aid to the origin countries of immigrants in order to decrease illegal immigration is focused on b) Economic development. This type of strategy is often a part of immigration policy adjustments and international cooperation efforts. It aims to tackle the root causes of irregular migration by improving the conditions that force people to leave their home countries. The approach includes implementing measures to foster economic growth, assist in peace negotiations, provide humanitarian aid, and ensure a functioning state that can guarantee the safety of its citizens. These efforts are intended to create conditions that reduce the push factors for migration, thereby reducing the need for individuals to undertake illegal immigration.
On the other hand, measures like effective border management policies can help prevent illegal immigration by deploying forces like law enforcement and border police, but these are not the only solutions required for comprehensive immigration reform. Addressing economic challenges through international agreements, increasing regional coordination, and creating pathways for safe and legal migration are crucial components as well. Additionally, reform initiatives like those proposed by the Congressional Jordan Commission of the 1990s suggest a switch in focus towards admitting immigrants with higher skill levels, thereby benefiting the labor market and government finances.
