From Alex Lawson, writing for Common Dreams:
	
Mitch McConnell and his fellow Republicans have a problem. They hate 
Social Security, because it is popular, effective, and doesn’t make any 
money for their billionaire donors. But their voters love Social 
Security. Ninety-four percent of Republicans oppose benefit cuts.
	McConnell understands the political dangers of being openly hostile to 
Social Security. So instead, he is plotting to sabotage it from within. 
The latest instrument of that sabotage is Andrew Biggs, a senior fellow 
at the billionaire-funded American Enterprise Institute. Biggs is 
McConnell’s pick to serve on the Social Security Advisory Board
 (SSAB) ...
	Biggs served as an associate commissioner of Social Security under former President George W. Bush and was instrumental in Bush’s push to privatize Social Security. ...
	Biggs supports raising the retirement age, and has testified before Congress that people should work longer. ...
Biggs also wants to turn
 Social Security from an earned benefit into a poverty-level flat 
benefit. That means huge cuts for middle class workers who’ve been 
paying into the program their entire lives. It would destroy Social 
Security’s political popularity by turning it into a welfare program—a 
sitting duck for Republicans to make even larger cuts. ...
     Biggs came under serious criticism at the hearing on his nomination.
    The good thing about this nomination is that the SSAB isn't much of a platform from which to launch attacks on Social Security. For better or worse, it's pretty obscure. Also, while Republicans like to talk about privatizing Social Security, raising the retirement age or turning it into something they can deride as "welfare," they have virtually no interest in actually doing anything along these lines.
