People are always willing to use the arguement that we need to import fresh slaves (immigrants) because they will do the work the natives are unwilling to.
No job is low paying if it needs to get done and no one is willing or able to do it. Constantly inporting fresh slaves to work cheaply is the reason why many native citizens are poor or unemployed.
Yet, today, America's leaders are reenacting every folly that brought these great powers [Russia, Germany, and Japan] to ruin -- from arrogance and hubris, to assertions of global hegemony, to imperial overstretch, to trumpeting new 'crusades,' to handing out war guarantees to regions and countries where Americans have never fought before. We are piling up the kind of commitments that produced the greatest disasters of the twentieth century.
— Pat Buchanan – A Republic, Not an Empire
