The Miami-Dade School District proposed to take 20 percent of the proceeds of all bake-sales, car washes and the like undertaken by school groups such as the marching band and math club. "But facing heat from outraged parents," the Herald reports, "Superintendent Alberto Carvalho backed off the plan . . . , which would have put about $5 million into the district account." Wow, that's a lot of Krispy Kreme Donuts. Wow, that's a lot of chutzpah.
