Which classification of criminals is primarily motivated by financial gain?

The classification of criminals primarily motivated by financial gain is correctly identified as economic criminals. This group engages in activities where the primary intent is to obtain financial benefits, often through illegal means. Economic criminals typically include individuals involved in fraud, embezzlement, money laundering, and other white-collar crimes. Their actions are focused on maximizing profit, which distinguishes them from other classifications of criminals.

In contrast, terrorists are motivated by ideological beliefs rather than financial gain, aiming to instill fear or promote a political agenda. Petty criminals may be involved in minor theft or vandalism but their motivation isn't exclusively rooted in financial gain, as their actions often stem from various factors, including impulse or necessity. Violent criminals typically perpetrate acts that intend to harm others or instill fear, rather than seeking financial profit. Thus, economic criminals stand out distinctly due to their clear focus on achieving financial success through illicit activities.
