Deregulation. Before the conservative revolution, banking was boring. Economic growth was high, and banks pretty much never exploded. It fucking worked. Now the banking sector involved in all of this weird shit that produces artificially inflated returns for a decade or so and eventually causes the world to explode. The economy is also growing at a slightly slower rate, and whereas this had all be relatively evenly distributed before, now it almost all goes to the 1%. Clearly, the latter situation is better.
