Does anyone really believe that printing more than one language on a government document accounts for a significant percentage of the federal budget?

If an industry found that their customers wanted interactions in more than one language would they be saving money by demanding that their customers speak a certain language? Or would they be serving their customers needs? Government offices should have the autonomy to serve their customers as each office sees fit.

Is having enclaves of groups that speak their own language really harmful to the US in anyway at all? Is the existence of Chinatown, Polish communities, Hispanic communities, Cajun areas, etc a problem that the Fed should even attempt some sort of social engineering forcing them to assimilate?

I think not and it certainly is not Libertarian to demand assimilation.

How can one believe in the free market, but have an exception for labor? Reason magazine has published some of their most recent addition concerning immigration on the web. See their homepage. We need to make it easier to immigrate oo the US legally. Our immigration laws are so complex and restrictive that it encourages illegal immigration.

There is a parallel to our drug laws here. Restrictive laws against something that people desire will be broken. The end result will be chaos. Our drug laws have resulted in an underground (and often violent) drug culture. Our immigration laws have resulted in an underground labor force. This underground labor force will not go away with stronger immigration penalties and laws. Instead more problems will result. We need to simplify immigration. This will make it easier to have secure borders because immigrants will be coming through using legal means instead of sneaking across.
