This is an interesting question! Philosophers who are actually working in their trained field are most often college professors and the pay will be in accord with their university. It can go from under $100,000 to above $200,000 if they are "star" professors and write books, etc. Psychologists' pay can also vary a great deal depending on the setting and specialty. A staff psychologist at a mental health center with a Ph.D. may earn $75,000. Or a clinical psychologist in a private practice can earn $200 per hour. At 1500 hours per year that would be $300,000 per year.
