|As a general solution to the problem that shouldn't offend anyone - except some of us anarchists of the more doctrinaire variety - why not charge everyone for the state services actually provided, with the option of a refund if one can demonstrate in court that one is not in need of them or already has a better alternative?|
Then let anyone come aboard who can pay up front for expected costs - burden on the infrastructure, fair share of the price of recruiting, maintaining, burying the Imperial Storm Troupers, etc. If someone wants to loan the entrance fee to some Haitian, Mexican, etc., great! That means that the costs are offset by the fee, while the only people who get in are those who are themselves productive or have demonstrated their value to someone else.
Note that while the first paragraph above makes perfectly good sense by itself, and should be consistent with an objectivist limited government, it is unlikely to pass muster before the political collectivists and deal swappers whose livelihood is strictly dependent upon keeping people at each other's throats. I.e., congress, the military, corporate industrial, patent stealing, academic complex.
However, it or something similar might actually fly with regard to immigrants in general. The U.S. needs people, people want to come here, what could be easier? Of course, the U.S. doesn't need more welfare mothers or terminally ill AIDS victims expecting to get free cadilac health care. So, require them to post a reasonable bond or purchase insurance. Whatever is a reasonable way to ensure that mostly the productive people get in.
