I think it's more #1 than #2 - the Big 4 obviously make a lot of money from Government and Defence in particular, but not to the tune of $15bn+. For example, PwC recent woes have revealed that they earn about $300m per year from the Federal Government. Say 75% of this is from Defence = $225m, x 3 (as PwC are the biggest of the big 4) = $675m. That's a rounding error in this spend.1, government ideology that the private sector do things better than government, and 2, the big 4 consultancy firms doing a good job convincing APS executives that they can do things that public servants can't.
I want to know who this money is going to.
Is it Serco et al?
