Bush allows contractors to pay lower wages

Of course, the only place I found this wire story was outside the US for the moment (as of late night on the 8th when I am writing this) rather than the corporate media here.

In a notice to Congress, Bush said the hurricane had caused "a national emergency" that permits him to take such action under the 1931 Davis-Bacon Act in ravaged areas of Alabama, Florida, Louisiana and Mississippi.
The Davis-Bacon law requires federal contractors to pay workers at least the prevailing wages in the area where the work is conducted. It applies to federally funded construction projects such as highways and bridges.

So let me see if I understand this correctly.
When the rebuilding starts, the contractors that are doing the work will probably need people to work.
Now these poor people are going to have access to a job, but making less than they could have made doing something else.
On top of that, how would you like YOUR house built by underpaid labor??
