I wouldn't lay the majority of the blame at Congress' feet, either.
It depends what the funded and unfunded budget requests were for Fort Bragg's yearly O&M budgets, IMHO.
It could be that the installation commander had a request in the system for facilities upgrades, and they were deferred due to deployment costs, etc.
I noticed when reading the news stories that the 4-button Vice Chief of Staff called the kid's father to express his disappointment and outrage, too. He mentioned that the improvements had been delayed in that particular circumstance. I've seen that happen a lot, funded requirements get changed to unfunded, and languish as a result.
That also means heads will roll in the food chain, and there will be a ripple effect as other Army and DoD facilities get scrutinized for condition and habitability. Then things will die down again, and moneys will be reallocated to other areas. It's happened before, it'll happen again. The local VA hospital where I do my stuff is still ramping up services and facility upgrades on teh heels of the Walter Reed scandal, it just took some visibility.
Problem is, the money now diverted to patch that one hole in the dike is coming from another bubble gum fix elsewhere.
