If your work is valued based on time rather than the quality of the product, it means you are a slave. Slaves can never produce a truly beautiful society because they can never do the work of craftsmen and artisans who are truly knowledgeable and love their work.

If Pope Julius II had commissioned 100 slaves to complete the Sistine chapel, it could have been done more quickly but it would have been done badly. Even if he had an artist tell them the design. Even Michelangelo hired helpers to help with the project but each helper was an artist or an artist in training, not a brainless labourer. Brainless, artless, loveless labour is one of the primary reasons human society has degraded.
