For example, abuse by the employers who, by defining normal salary as bonus, thus reduce the average severance package they have to pay to "let people go" (few actually have golden parachutes, and normal severance packages are based on basic salary only). If the system abuses workers, in avoiding to provide legitimate protection the workers are entitled to, is it surprising workers abuse the system? I'm afraid not. This does not legitimate abuse, but that may explain why it appears.

It is often said that the incentives are wrong in investment banking because employees have a call option: they get a share of the profits they may generate but they do not share the load of potential losses. This is a legitimate concern. However, funnily enough, financiers know how to value a call option. They know the value increases with volatility (higher profits and higher losses translate on average into higher bonuses since only profits count) hence the wrong incentive of always looking for more risks and leverage. It is easy to counteract this (while also ending the abuse mentioned in the previous paragraph): swap a substantial or integral part of the bonus with a fixed premium (the option price). If traders were to earn fixed and high salaries (instead of a low base + large bonus), the incentive would naturally move to keeping the job. To keep the job would mean finding the balance between two antagonist consequences of risk: one's job exists if it is profitable (which in finance requires taking some risk), one's job exists if it is profitable (which means risks are controlled enough that they cannot blow). If traders lose their job when they lose more than some pre-allocated capital (not the current state of the world), risks in the industry will be controlled tightly.

I addressed earlier why bonuses were useful to motivate talented financiers to work for others rather than only for themselves. A solution different from bonuses is simply to pay these financiers decently for the hours they put in to keep risks controlled (no joke: try discussing with an adoption agency about your working hours when you're a trader. The agency will immediately consider you're working too much, to an unacceptable degree, and that you're probably not suitable parenting material. You didn't even start the assessment process yet!). Again, the fair price is the value of the call option (on the notional the talented individuals can trade if they're independent, so we're unlikely to talk of a call worth millions).
