The article at first glance is focused on the issue of the impact of immigration on population numbers:
…projections show that the U.S. population will grow by 135 million in just 42 years — a 44 percent increase. Such growth would have profound implications for our environment and quality of life. Most of the increase would be a direct result of one federal policy — immigration. If we reduced the level of immigration, the projections would be much lower. The question we have to ask ourselves is: Do we want to be a much more densely settled country?But, stealthily, it gets round to the key economic issue:
While immigration does significantly increase economic activity in the receiving society, almost all of that increased activity go to the immigrants themselves in the form of wages and benefits. The gain to natives is tiny…When will the Pro- Immigration fanatics at The Wall Street Journal show similar fairness?
Moreover, this tiny economic benefit was entirely erased by the fiscal drain immigrant households imposed on taxpayers. Perhaps worst of all, the researchers found that to generate this small gain, immigration reduced the wages of the least educated and poorest American workers.
