The entrepreneur who lives on the labor of others is often referred to as a rentier or sometimes criticized as a capitalist in certain contexts.

Explanation:

• Rentier : This term describes someone who earns income primarily from owning assets or capital rather than actively working. In economic and social theory, a rentier benefits from the labor of others by collecting rents, dividends, or profits.
• Capitalist : In classical economics, a capitalist owns the means of production and profits from the labor of workers. While this is a neutral or positive term in many contexts, critics sometimes use it to imply exploitation.

If you are asking from a critical or Marxist perspective, such an entrepreneur might be called a bourgeois or exploitative capitalist , emphasizing their profit from others' labor. Would you like a more detailed explanation or examples?
