Various ideas have been applied to a global view of migration, such as the ideas of other journalists such as Johnathan Wolff and Avnir De-Shalit to migration. Wolff and De-Shalit's state that the use of law and ethics is a positive factor in the debate over free migration. The debate of free migration does not apply to a specific country but extends beyond, and continues on to a broader spectrum for introducing a freedom of movement amongst all people, for all countries. However, this concept is especially significant to the places that experience the most migration-including both host and receiving countries or states.
