The defenders of slavery had passed the arguments used to challenge the system.
Explanation:
The arguments used to challenge this system are
Some people in the south argued that slavery was actually good for the slaves. Many of them believed that slaveholders providing these 'lesser beings' with religion, sustenance and shelter was an act of kindness towards them.
Equally, many in the south believed that slavery was preferable to the factory work and people can do in the north.
Most of the people were worried that without slavery, the economy would crumble. Several elements of trade and production were reliant upon slavery, and so many southerners argued that slavery could not be abolished, in the interest of prosperity.
The question which both John Maynard Keynes and Karl Marx would agree most about would be D. Do free-market economies create problems for workers?
<h3>What is a Free Market?</h3>
This refers to the economic system where there is limited government interference and price is determined by private businesses.
Hence, we can see that based on the economic views of both Keyes and Marx, they both questioned capitalist production and they would likely ask the question in option D because it would show how efficient it is for workers.
