The fence is gone. That is the whole difference, and it is the difference between equity and inclusion.
In Fig. 5.3 the tall wooden fence stands in both panels. Equality gives the man, the boy and the small girl one identical box each — and the girl still cannot see. Equity redistributes the boxes: the man on the ground, the boy on one box, the girl on two — and now all three can see. The barrier was never touched; it was climbed over.
In Fig. 5.14 the same three people — the man, the boy in yellow, the girl in pink — stand on open grass with no boxes at all, arms raised, watching the cricket match directly. There is nothing between them and the game. And in the field itself, girls are playing alongside the boys.
Fig. 5.15 makes the same point for a playground. In the upper picture the ground is rough, stony and uneven; the boy in the wheelchair sits at the edge with his back to us, watching the others swing, slide and run. In the lower picture the ground has been levelled, the swing has a proper seat with a back, and the same boy is in the middle of the game with the ball in his hands. Nobody gave him extra equipment to cope with a bad playground — the playground was designed so that he could play. That is why the caption reads “Designing and creating facilities that are inclusive”.
