President Obama has budgeted $17,613 for each of the estimated 75,000 Central American teens expected to illegally cross into the United States this year, $2,841 more than the average annual Social Security retirement benefit, according to a new report. The total bill to taxpayers: $1.3 billion in benefits to “unaccompanied children,” more than double what the federal government spent in 2010, according to an analysis of the administration’s programs for illegal minors from the Center for Immigration Studies. The average Social Security retirement benefit is $14,772.
