I believe within da next decade or so the westerners would halve the migrant populations in the west by just tightening the screws a bit. Many are fleeing cuz the cost of living is already unbearable. As benefits/ social welfare/ medicare/ blocks on family members migrating get enforced, the whole fluff gets blown away exposing the core exploitative nature of da policy.
Most don't understand the premise of this 'immigration/ illegal migration exploitation'. The west uses our youth from the third world and builds capital, whilst our countries left with sweet fukk all to show for.
