If trying to solve a problem one way just doesn't work, and it's been tried for a long enoughtime (most of the last century in this case), and it's ended up making that problem even worse, and giving rise to other problems, the sensible thing is to see if a different approach might work better.

And when that doesn't happy, it's a good idea to take a good long look at the present situation, and at who it is that benefits from keeping on with the approach that has failed us so badly.
