The worst of that system is that once the CFI or CFII is on your licence you never actually have to have a training job to keep it. One guy I met was a Chief Pilot of a twin turbine outfit with an IFR capability with a CFI and a CFII rating but despite his advancing years had never ..... never.... seen the inside of a cloud.
I also met a company FSO who was in despair because the Ops Director's first port of call when looking for TRI candidates was those with a CFI rating. It was proof that you can earn more if you invest in a CFI course but the notion that you have to be able to do the job as 'teacher' was lost on the way. Shameful.

PS . Yes I know it's different under EASA but those who work under FAA or similar will know what I mean.
