Hospitality for our Guests

What is the point of a guest worker program? By nature of having the program, our government is admitting America's dependency on cheap imported labor, and why do we have to spend so much time and money rounding up workers in Mexico when we already have so many guests here? In Mexico, huge billboards suffocate the roads with claims of work in the fields of North Carolina. Gangs and other forms of organized crime pose as legitimate guest worker agents and manipulate the already impoverished farmers to milk them for money with the promise of a job in the land of plenty. Our efforts in their country have already and are continuing to create strange and detrimental social dynamics and frameworks prone to corruption. Meanwhile, we have a "guest" population already here, and we know who and where they are. Why don't we divert more effort into treating our current guests with a little more hospitality before inviting more? Legitimizing our current population, through a "guest" program or otherwise, is a necessary and overdue step, and diverting any more funds to the lethargic, bureaucratically handicapped, logistically challenging process that is the guest worker program is a waste.
