”Well, people claim, if you have a welfare state, the masses of the world will flood into the USA just to collect the welfare state’s ‘free stuff.’ But why let them? Even under currently existing rules, undocumented immigrants are ineligible for nearly all welfare-state benefits. If a flood of immigrants will break the welfare-state bank, why not simply make immigrants ineligible? Case closed. In that case, the opponents of immigration claim that making the immigrants ineligible for welfare-state benefits won’t work because they will find a way to get the stuff in one way or another. But this objection is, in effect, a declaration that the state is incompetent — which is not exactly a news flash, to be sure. So the anti-immigrationists insist that instead the government must ‘close the borders.’ Notice, however, that in this case the anti-immigrationists, having just insisted that the government is too incompetent to exclude ineligible immigrants from welfare-state benefits, now presume that the government is so competent that it can keep undocumented immigrants out of the country.”
OK. So if the government is so incompetent that it can’t, just can’t, keep people out, why do anti-anti-immigrationists expend so much energy trying to stop the government keeping people out? Isn’t it because, all the “If you build a 50ft wall someone could build a 51ft ladder” waffle notwithstanding, they know very well that governments, when they put their mind to it, are anything but incompetent when it comes to keeping people out? Otherwise why make such a song and dance out of it?
