"Is there any place in America whose people, from its top officials on down, do a better job of shooting themselves in their own feet?"
No, there's not. I hate to say it but watching this train wreck on a daily basis leads me to believe that Orleans Parish needs to be federalized. That would solve 99% of the problems. Just take the damn thing over for the next 10 years, boot out the race pimps and numbskulls who couldn't run a lemonade stand much less a city of half a million people and run it like any other city that operates in a "normal" fashion.
Otherwise, don't send those IDIOTS one more dime.
Chicago, Detroit, Pittsburgh, Washington DC, and Baltimore also spring to mind, as does San Francisco... oh wait, they voted to ban guns, never mind...
Sadly, "federalizing it" would only mean that federal government race pimps and numbskulls would be appointed, rather than the home-grown ones they have today. I mean, what competent person would want to take on a job like that?
