Here was Brasil's solution in the middle of last century when I resided there.
In rural, agricultural areas the employer provided the housing, the schools and the school supplies for their employees and their employee's family, whether full time or seasonal. The state provided the school teachers, emergency medical care and medical clinics. The housing and the school facilities had to meet prevailing state codes and the employer provided transportation for medical treatment.
The system worked well and Brasil had a higher literacy rate than the US at that time. Brasil's level of medical care was technically inferior to the US, resulting in higher infant mortality rates, but a higher percentage of the population was under routine medical care.
The system had only one, minor irritation. Any invitation from the state to participate in prophylactic medical procedures, such as inoculations and health assessments, was extended and enforced by armed military personnel on an in-your-face, right now, door to door basis.
I have friends in the sugar business here in Florida,and elsewhere.
They used to import cutters from Haiti to work the fields, great employees.
These workers were provided with housing, medical care, food, and education for their kids.
Obviously, the towns surrounding the sugar cane fields thrived during the "zafra" (cutting season), selling all the things these workers needed.
Some bleeding heart liberals, backed by immigration control advocates, managed to make the practice of bringing cutters in from Haiti financially detrimental to the mills, in order to protect these workers from being exploited.
The industry reacted by mechanizing the process.
Now the cutters live in abject poverty in Haiti when before they made an excellent living by Haitian standards, their kids are (most likely) not getting an education, and they can't afford medical attention.
Needless to say, the town surrounding the mills suffered as well from the loss of business.
I think that there is absolutely nothing wrong with a good guest worker program, and I can't for the life of me figure out how to remove ten to twenty million people from our soil effectively, and without making us look like we are conducting something akin to ethnic cleansing.
