Cookie cutter 'everyone gets the same education' means nobody brings anything new or unique to the table in the workplace.

Dramatic 'experiments' in education like this seems like a good idea. The end result will be more variety in how people are educated and how they act in adulthood. In the same way companies push diversity because studies show more diverse teams have higher economic output, diversity of education probably has similar benefits.
