I was in NO two weeks after Katrina and have been back several times, and have family and friends there. The problem is not that nothing is being done; it appears that the problem you have is that much of what is being done can't be seen just yet.
You said you were there to bid on a project. There are many, many other projects being bid on right now as well. Many of those projects depend on federal aid or insurance proceeds. These things take time. The last time I was there (about mid-January), there were numbers of small groups of carpenters and construction guys doing renovations on houses, in general following along behind the insurance adjusters who were basically going from house to house, neighborhood to neighborhood. As soon as insurance terms were agreed on, checks were issued, and renovations starting. In some neighborhoods, it looked like a very busy beehive.
Not all neighborhoods are like that of course. The areas that were the worst flooded (i.e., the 9th Ward) will take a longer time to re-build, largely because of the numbers of now absent landlords, and importantly, the public policy questions about exactly how or what the shape/dimensions of rebuilding in those areas should take.
Yes, the Fed govt is moving slow in some areas (the last I heard (a few weeks ago), the EPA had still not given permission to remove all those 'drowned' and/or abandoned vehicles), but don't mistake the lack of visible progress for no progress at all.
Six months is not long for an effort of this magnitude. The number of local political jurisdictions alone is a major impediment to prompt action - every politician has to get into the act, as witness Nagin's posturing.
Your opinions are your own, and you are certainly welcome to them. But look, in this post as with so many others, you give the impression of just grabbing at anything as an excuse to exercise your Bush Derangement Syndrome. Your hatred of Bush appears extreme and just cannot be healthy - it seems to color everything you do or post or well, everything. Your almost like some of those Repubs were over Clinton!
