Los Angeles unveils $578M school, costliest in US

The K-12 complex to house 4,200 students has raised eyebrows across the country as the creme de la creme of "Taj Mahal" schools, $100 million-plus campuses boasting both architectural panache and deluxe amenities.

"There's no more of the old, windowless cinderblock schools of the '70s where kids felt, 'Oh, back to jail,'" said Joe Agron, editor-in-chief of American School & University, a school construction journal. "Districts want a showpiece for the community, a really impressive environment for learning."

Not everyone is similarly enthusiastic.

"New buildings are nice, but when they're run by the same people who've given us a 50 percent dropout rate, they're a big waste of taxpayer money," said Ben Austin, executive director of Parent Revolution who sits on the California Board of Education. "Parents aren't fooled."

At RFK, the features include fine art murals and a marble memorial depicting the complex's namesake, a manicured public park, a state-of-the-art swimming pool and preservation of pieces of the original hotel.
