Does simplified work? Subway maps

The Metro system in Athens is mostly clean and efficient. Although my Greek is still barely remedial, the clearly marked subway line map on every train is essential to finding my way around the city. It is simplified. It is organized.
It's like our school systems. 
Notice how you can switch from one line to the other?
You can clearly see where you are going and how to get there.

The problem is that the actually location of these Metro stops looks like the map below. Now THAT is complicated, but still organized. THIS is our education system. In between the green, red and blue lines lie people, children and adults, who don't learn in a standardized way. How do our ecosystems reach them and help them move forward?

Second Chance School students attend classes several nights a week after a long day of work and family.

Options like the Second Chance School of Piraeus help adults who didn't finish high school. Although the structure of the program requires commitment and drive on the part of students, many of the core beliefs of the program should be adopted by all school systems.
An option that lies within the system is the Perama Technical High School. Students who struggle with the robust requirements of the traditional Greek lyceum (traditional high school) can find success and belonging here. Students choose from one of five career clusters and in three years most have a certificate or can begin an apprenticeship.
The system of belonging in each of these schools deserves closer examination. However, a central question must first be addressed: How can we change the structure of an education ecosystem to work for all students rather than push them forward until they fail and drop out of the system?
I've spoken to parents, teachers, and students and many agree that the requirements of Greek high schools are out of touch with the needs of 21st century learners. Over and over in conversations the question of "Why learn ancient Greek?" is asked. While I don't have a full answer to this question yet, it definitely leads to an inquiry path. Can the structure of an education ecosystem be flexible and responsive or must it be rigid in the name of rigor?
