What they really find out, is that the 10% or 15% override they thought would cover their overhead, is a totally bogus number.
They soon find out what they have on their hands is a classic pyramid scheme. Now they have to constantly get more installers to sign up, and work a couple weeks while waiting on their first checks, to pay the existing techs, and it snowballs from there.

That is why you see DTV companies constantly looking for fresh meat, oops, I meant new installers, to fund the bottom layers on their pyramid to nowhere.
