Many Americans detest the border crasher's due to the perceived strain on an already over-strained US economy. Believing the immigrants take jobs from Americans. As for unemployment strains to the economy such positions are unwarranted when one realizes, while they do take pay for the work, the work they provide is of equal or greater value to the economy. The real strain comes from the now world wide belief if you come to the US we will give you free money. The current social state in the US is the problem and it precludes us from taking on millions of immigrants who desire a free ride, compared to the immigration during the late 19th and 20th centuries.
