Answer:
- In the 1920s, there was a HUGE technological advance, meaning people were starting how to program and build machines, and using those newfound skills to their advantage,
Explanation:
Basically, people built machines to do work faster, which made more products, which meant more customers. People didn't have to spend a huge amount of money to profit a huge amount of money. That means poor/unemployed people got jobs, and it went down like clockwork, as more customers came, they needed more people, making more jobs, making more money, making the economy skyrocket.
