I'm saying they are 5x more expensive than they need to be. So most of the money that goes to the agencies is de facto corruption, even if it goes to the workers who are working, but ouputting not much.
The rate cards we use are tied to market rates. Consulting (and services businesses in general) aren't super-profitable.
I think probably you're just pulling numbers out of thin air.
Now if you think that the value of consultants is overrated, I tend to agree with you in some - but not all - cases. As an example, it makes little sense to hire FTEs for a short term project that has to happen on a discrete timeline.
