Once again, attempt is being made to treat legal and illegal immigration at equal footing. If you look at the map, you will find that GCC nations such as Saudi Arabia and Kuwait do have a higher proportion of migrants to the population. But the plus point here is that all of them are legal migrants. Illegal immigration is a punishable offense in most of the countries (unlike the case in USA, where illegals are provided with funds from taxpayer money). This is an issue that is present only in the US/EU. And the only reason is lack of enforcement of laws by the left-wing.
