Economics of dropout rates

EdNews Junkie posts and interesting comment on both my blog and Gewertz'. Here's my response:

Junkie,

No doubt you are right about the economics of dropout rates and test scores. Clark County was the fasting growing county in the nation. They were building new schools hand over fist, even before there were any communities to support them. Now Nevada has become the state with the fastest rising foreclosure rate in the nation and Clark County leads all counties in foreclosures.. Time to rethink validity of state accountability measures and the notion that schools alone must shoulder the entire responsibility for reform.
