A California businessman started a check-cashing service, operating out of a large commercial van. He charges customers 1.5% of the face value of the check for the service, and he has plenty of customers, mainly people on unemployment, welfare, social security, and disability, who lack the bank accounts and credit ratings necessary to cash their checks in a bank. His profit is estimated at almost $50,000 per year. He feels there is nothing unethical about his business. Do you agree? Why or why not
