Which of these occupations do you think is an honorable way to earn a living? Why?
Hmmm...
This question begs of many further legitimate inquiries to follow...
1) Is "earning a living" an establishment of an "honorable" status?
2) What was Mahatma Gandhi's "occupation"?
What was Jesus' "profession", and what "earned living" did He evince in being "honorable"?
3) Is an unpaid (or uncompensated) painter, sculptor, musician, author, or teacher--"earning an honorable living"? How so, or not so?
4) A plumber provides a skilled service (involving physical labor) for monetary compensation. Is this an "honorable" profession? How does this particular skill fundamentally differ from the one offered by a prostitute?
5) Is sexual prostitution fundamentally a "dishonorable" profession? Why?
6) Do paid assassins qualify as being "honorable" within their profession, if they consistently fulfill their contractural obligations?
What of ordinary soldiers in times of war?
7) Are CEO's of major corporations "earning an honorable living" when they fire thousands of employees in order to satisfy requisite profit margins, or shareholder expectations?
Answer me those questions, and then I may better answer whether or or not there is any "honor" in "earning a living" by the varied options you offer as example...
