Yes, the wave of Irish immigrants did end after many years of basically open immigration and there were people stamping their feet and turned red in the face the whole time that was going on as well.
And they were right. The Irish took over whole communitys and in some cases basically whole cities; driving the God fearing honest real Americans out. And we see where that has brought the nation today! St. Patricks Day and our children eating Lucky Charms ceral.
Because of their much lower education levels, Mexican immigrants earn significantly less than natives on average. This results in lower average tax payments and heavier use of means-tested programs. Based on estimates developed by the National Academy of Sciences for immigrants by age and education at arrival, the lifetime fiscal impact (taxes paid minus services used) for the average adult Mexican immigrant is a negative $55,200.
• Although they comprise 4.2 percent of the nation’s total population, Mexican immigrants and their U.S.-born children (under 18) account for 10.2 percent of all persons in poverty and 12.5 percent of those without health insurance. Even among Mexican immigrant families that have lived in United States for more than 20 years, almost all of whom are legal residents, more than half live in or near poverty and one-third are uninsured
• Even after welfare reform, an estimated 34 percent of households headed by legal Mexican immigrants and 25 percent headed by illegal Mexican immigrants used at least one major welfare program, in contrast to 15 percent of native households. Mexican immigrants who have lived in the United States for more than 20 years, almost all of whom are legal residents, still have double the welfare use rate of natives.
