“It is worth mentioning that the core concepts of the immigration law, as we have it now, have been shaped in years 1917–1924 by the same politicians who voted in Prohibition in 1919. The same arrogance that a majority can impose their political will on the rest of the society prevails. The same majority had an illusion that they had a mandate to use government policing powers to coerce others to abandon activities that in general are moral, such as having a drink or hiring a foreigner, just because they had the political power to declare it illegal.

Prohibition was repealed in 1933; our immigration law, with several nonessential modifications, still stands. Behind it is the same political wisdom that brought us Prohibition. It is as easy to implement, and as easy to enforce, as Prohibition was.”
