You cut off the teet they are sucking on.

When there is no more food they will go elsewhere to find food. They can go to a different country that will support them or they can find a job. Either way it will not be easy, crime will sky rocket temporarily but it is the only way we can fix this country.

My guess is that if you put a halt to all entitlements to anyone who is not physically disabled or under the age of legal retirement within a decade you would see employment numbers at all time highs and ghettos will become almost non existent since those who refuse to adapt will either be dead or in prison.
