Step-by-step explanation:
People who become rich unethically and start with an 'r' and end with an 'n' are often referred to as 'ruthless capitalists.' These individuals accumulate wealth through unethical practices such as exploitation, fraud, or corruption. Examples of ruthless capitalists include individuals who engage in insider trading or manipulate stock prices for personal gain. While some may argue that these individuals demonstrate ambition and business acumen, their methods and actions are considered morally objectionable and harmful to others.
