Incentives manufacture their own perversity. Take for example expensive signalling: any incentive system with strong incentives will trivially have paradoxical effects in any situation where expensive signalling is common (for example, within middle classes, teenagers will join social groups that involve explicitly avoiding gainful employment as a means of demonstrating group loyalty -- hence punks, goths, and stoners).
