Many of these companies might not even exist. You have no way of knowing.
You know, I've been waiting for something like this. My Father-in-Law is a project manager, he manages the Voyager and Ulysses projects for JPL NASA. Technically, he works for Cal-Tech, and has to audit both of these missions annually. He has been to visit most of the vendors on both missions; Cal Tech has sent him to Germany, Greece, and the Netherlands to oversee some of the vendor work.
I can assure you, he is not part of the consipiracy - he is a Tuskegee man - and a Tuskegee man could never be 'The' man. I can also assure you that he gets paid, that his entire mission teams get paid, and the vendors get paid - every last one of them on his projects.
So where is the motivation for the conspiracy? All the money is going to individuals.
