See here for one of many media discussions of the 50th anniv. of LBJ's announcement of the War on Poverty.
One of the aspects that I haven't heard discussed in the current round is the use of the 'war' metaphor, although that's been written about before. See also, e.g., the War on Drugs, though the War on Poverty had significant successes, which I don't think -- although I'll stand open to correction -- the War on Drugs did.
Added later: Loomis says today we'd largely have to call the war on poverty lost. An overstatement. E.g. the kind of malnutrition that existed pre-'64 in Appalachia and elsewhere is considerably less prevalent in the U.S. today -- not gone, but less prevalent. By the way, why only 188 comments (at last look) on the Loomis post? It's LGM, after all; shouldn't there be at least 6,789,444,567 comments? Loomis writes, for the most part, serious posts, but I occasionally wonder what it would be like to blog at a place where you can write virtually anything (except Farley's videos of his talking-heads exchanges) and get a fair number of comments.
