You ask an important question. Essentially, we see it as deferred compensation, not necessarily wages. We see compensation as a promise made in a way similar to the promises made by that same organization in a number of different domains. The promise, upon receipt of a service, to pay for that service is also akin to that, which is where you find other unsecured creditors.
In an insolvency process we need to be able to look at all those who, essentially, have IOUs and promises held, and figure out a mechanism by which to provide for an orderly treatment of those. While we've deemed what's in the fund as absolutely sacrosanct, what is not in the fund is held to be akin to that, which is other creditors and their unpaid bills as well.
