What a difference money makes.
I think this is a cynical and shortsighted perspective. The idea that a primary reason for NOLA's Katrina woes was "they wuz jus po' folks so nobody cares" is wrong, IMO.
There are a number of very important differences between the SoCal and NOLA disaster responses, the least of which is "money":
1) SoCal obviously has LEADERSHIP. NOLA was betrayed ultimately by their incompetent mayor and governor, not the eeeeevil Federal government ("George Bush hates po' peoples!").
2) SoCal had planning and a sense that "the big one" really could happen, due to their experiences w/ earthquakes and previous fires. Despite the warnings of a few
Cassandras, few thought that NOLA would ever really get hit w/ the big one. Year after year the big storms had veered away, inducing complacency.
3) The NOLA residents most affected by Katrina had adopted a culture of dependency and living off the government teat. This is the ultimate result of the PHRASECENSOREDPOSTERSHOULDKNOWBETTER. policies of the "war on poverty", which (adjusted for inflation & per-capita) really hasn't helped poor people in a statistically significant way. While there is certainly an element of this in SoCal, not everyone there has been infected with the same PHRASECENSOREDPOSTERSHOULDKNOWBETTER. disease suffered by the majority of the California legislature.
4) The state and Federal agencies learned from NOLA's experience and did a better job this time around. Now they get criticized anyway, as being more interested in "rich" people. It's a no-win situation for them: if they don't do better in SoCal, they get ragged for not learning from past mistakes; if they do better in SoCal, they get ragged for catering to "rich" people.
Personal story: a couple my wife and I know had moved to the Mississippi coast a couple years before the Katrina disaster. The woman got a good job there so they moved. When Katrina happened, they evaced in time and came back here (Atlantic coast) to stay for a while and regroup.
This couple is very liberal politically and they ravaged the "evil" George Bush for his obvious hatred of po' folks. I asked them how they managed to escape. They said "we got in the car and left when things looked bad". I showed them the photos of swamped, unused buses in NOLA and said "the local leaders kept those buses parked and ordered everyone to the dome. Stop being ruled by your emotional politics and embrace reality. Inciting class warfare will only get you so far".
