There is one big difference between what I advocate for children in dysfunctional homes and what Weingarten is proposing.
I am aiming for a completely privatized system of K-12 education. In a private system some children would be homeschooled. Some would use on-line programs. There would be dame schools and one room school houses. Some larger day care centers would offer 1st, 2nd, and 3rd grade. There would be Waldon schools, Montessori schools, and Challenger Schools. Some children would attend boarding schools, and others would attend the typical brick and mortar (prison-like) school. Parents would be completely free to choose the schooling that best suits their child's needs and that would be most convenient for the family.
The KIPP model of schooling would be one of likely hundreds of options open to parents.
Weingarten is essentially prescribing a one-size-fits-all cradle to grave communistic welfare system for all children.
....as long as they could afford it.
