Answer:
After the increase in technology, machinery and equipment became the most valuable sources of capital.
Explanation:
During Pre-Industrial societies the most valuable sources for generating income and wealth were Land and labor. Anyone with abundant agriculture land could hire people to work on them and earn a good living.
However, with the industrial revolution, automation and efficiency became more valuable and only those who could employ and run the latest machinery and churn out high-demand products, would become wealthy.
