CAQ school for four-year-olds meets resistance

Does anyone really understand the CAQ obsession with getting four-year-olds into formal classrooms? Other parties are pushing back and talking about the cost and the shortage of teachers.

Even though the CAQ just made a point of cutting school taxes, it’s promising 250 new classes for next year.

I recall François Legault being obsessed three years ago with the idea of making kids sit in school from 9 to 5, and having school be obligatory till age 18, “to reduce the province’s high dropout rate.” At the time it sounded like lunacy to me, and it still does. Does anyone see any sense in it?
