Well the fine system should augment the rest of the measures. It's not as if you can keep doing what you are fined for. The punishment for repeat offence should and does result in escalation of punishment.
The issue seems to be two fold:
The fine system did not keep up with reality and the insane income inequality. If fines are setup to hurt equally, like a percentage of global revenue, or of total assets, you can bet your ass they will be effective at stopping undesired behavior.
The lack of shame, it used to be that getting a fine would actually serve as a signal people understood, but the corporate shield from personal responsibility has gone so far that decision makers just do not care about potential consequences.
