Unauthorized workers helping prop up Social Security, Medicare

Although it has been reported before, a new report confirms that people working with incorrect or mismatched Social Security numbers are paying $9 billion a year in federal taxes. It is likely that most are immigrants working without authorization in the United States. They pay into Social Security and Medicare, but federal law prohibits them from collecting Social Security or Medicare benefits. Since the federal government profits off of this, does anyone wonder why the government has been slow to enforce immigration laws? Of course, this doesn't even touch those who are working under someone else's Social Security number, perhaps even yours. So if your next Social Security earnings statement shows you having far more income than you remember earning, there could be someone else working with your Social Security number, but you will see the higher benefit when you retire thanks to their work. I guess not all identity theft is a bad thing?
