Some crimes have huge consequences, like murder for example.
Crimes with big consequences generate strong response from the enforcement agencies. At the present, the enforcement agencies are much stronger and at least somewhat smarter than vast majority of criminals. Therefore, assuming that one will not be caught for a serious crime, is likely a mistake. But getting caught is not the only consideration. A mere suspicion will often be enough to ruin a reputation. In a wealthy and ordered society, good reputation is likely worth more than proceeds of a random crime.
