Working in data processing (I.T.) nowadays while in the USAF at a command base I had a Secret (Not Top) clearance. I would imagine there are more people here than you suspect that have had some level of clearance in their past.\n\nI still have a Secret clearance. There are two criteria to be satisfied to access classified information: the requisite security clearance and a "need to know". You can have a "super-duper-top 'o the heap-secret" security clearance, but if you have no need to access information classified as merely "secret", you ain't seeing it.
