Here is a great starting place for a useful debate. From Politico: Why FEMA is making a big mistake in Puerto Rico. The agency is proposing one mega-contract for delivering relief to the island. Here’s a better way.

I agree completely, based on experiences with lots of large disasters worldwide. As an appropriate US example, i point to the work of ICF International in running Louisiana’s Road Home Program. The myth is that one giant private company can inherently run such efforts better than government can. Road Home would have been much more successful if organized according to the decentralized model that these authors suggest.
