Final answer:
Business owners and middle-class professionals benefitted most from industrialization due to wealth creation, while workers faced difficult conditions and lost control over their working conditions.
Step-by-step explanation:
In my opinion, the group that benefitted most from industrialization was the business owners and middle-class professionals of the eighteenth and nineteenth centuries.
Capitalism and industrialization enabled these individuals to create tremendous wealth through mechanization and increased production. They had access to new consumer goods made cheaper by industrialization.
However, these benefits often came at a high cost to workers who had to work long hours in difficult and dangerous conditions. The workers lost control over their working conditions, and their wages remained low.
