Is the overhead in deciding who gets free lunch and who doesn't and then managing the debt really saving more money than just giving all public school kids free lunches with no strings attached?

It's nominally 20 pages but the first five are boilerplate and ToC and the last ten are a listing of how much each school district received, so you could reasonably read all the actual report.
