SS to turn negative in 2015

"One very possible outcome is that 2013 and 2014 will bring (more or less) what we have in 2011/12. AKA Stagflation. Ladies and Gentleman that would be an unmitigated disaster. Should we have more years of stagflation, the net surpluses (includes % income) at SS would fall to zero in 2014 and be negative in 2015. Once that line is crossed, it rapidly collapses. It's nearly impossible to reverse."
