Don’t discount the role of lawyers in this. Take a look at daytime TV and you will see a steady stream of commercials from lawyers promising to get you the disability benefits you deserve.
the key is anxeity /depression claims/bad backs etc. the Obamaphone crowd is flooding the system with claims that cannot be proven or disproven by any physician
“You’ve paid into the system your entire working life. Now get the benefits you deserve! No fees until your case is settled.”
