That’s absolutely what the governments want you to believe and is definitely happening as a direct result of European and US migration/refugee restrictions. Freedom of movement should be a basic human right.
They have literally used trafficking charges against humanitarian aid workers and academics that were attempting to help refugees at and around the southern border of the US.
The reason human trafficking is possible for the most part is that there’s no legal route for the vast majority of refugees to get to the countries of migration, causing a huge illegal network and the opportunity for increased levels of human trafficking especially against the most vulnerable.
If legal pathways were more accessible this wouldn’t be a problem. I try to find the root cause rather than the bandaid solution. As we’ve seen from the war on drugs, the bandaid solutions don’t work.
Besides, if you had ever read migrant journals or any other type of primary document concerning this type of situation, you’d know that a bunch of people getting ushered into the back of a truck isn’t exactly uncommon. Further, no undocumented migrant has their papers in order. That doesn’t really change much.
