Immigration

I have come up with a few answers for objections to open borders. Any other objections and/or answers would be greatly appreciated.

• You can never close the borders. People managed to get across the Berlin Wall and it was more heavily fortified than we can ever hope to make our borders.
• Immigration is similar to gun control. Gun control doesn't work because bad guys will get guns no matter what the law says. Good people are left defenseless because they can't get guns. Strict Immigration laws makes it harder for decent hardworking immigrants to get in while less appealing immigrants will simply ignore the restrictions. (Of course, be sure this person is opposed to gun control before you use this one. They probably will since conservatives generally support closed borders and oppose gun controls)
• We cheered when Reagan told Gorbachev "Tear down that wall." Does it make sense to support building our own wall now? (You may wanna make sure that they like Reagan before you use this one. They probably will since it is usually conservatives that support closed borders)

• "They'll go on welfare." Well, one solution is to end the dole for everyone, including Americans. Alternatively, immigrants are not citizens; therefore, there is no requirement that they be permitted to be on the dole. Thus, if "no dole" was an express condition of immigration, immigrants who would come to the U.S. would be the types we want people who like to take risks, work hard, and be self-reliant and independent energizing qualities that every society should cherish.
• "They'll enter our public schools." Then, prohibit them from doing so. The result would be that they will form their own private, independent schools and, consequently, provide the nucleus of a new type of person in America: an independent thinker who loves knowledge for its own sake, unlike the public-school student, who simply learns how to memorize and obey.
• "They'll take jobs away from Americans." Every American who works today does so under the assumption that he can be replaced with a worker who has moved from another state. All that open immigration would do is open the market even more. But with one big benefit the new spending by immigrants would open up a wealth of new employment opportunities in the businesses that would have to open or expand to meet the new economic demands.
• "They'll dump their products on Americans." Then, retaliate by dumping your products on Americans or on foreigners consumers will love it! More important, when a person opens a business, he does so under certain risks. One of these risks is that someone else might satisfy the consumers better than other sellers and that this might happen through low prices or even free goods being given to consumers. If a businessman does not want to take that risk, then he should not go into business.
• "They'll get their governments to subsidize their reduced goods." Again, this is a risk that exists in the business world, even domestically. Unfortunately, we live in a world in which people permit their governments to plunder them in order to give a dole to others, including businessmen. No one forces someone to open a business. If a person does not want to take the risk of a government giving a competitor a dole, then there is a simple solution: do not open the business.
• "Millions of people will immediately move to the United States." Perhaps. But we must first keep in mind that U.S. government import restrictions create miserable economic conditions in many countries that encourage people to want to emigrate. Once those restrictions are lifted, there is a probability that with the increased economic prosperity in foreign countries, many would-be emigrants would choose to stay at home among friends and family. But if millions did come, great! History has shown that cheap labor, like cheap goods, is a tremendous economic boon to the people of a society. Give us your tired, huddled masses yearning to breathe free and watch economic prosperity here soar!
