Question

When an industry was monopolized by one company or trust during the Gilded age, what happened to workers wages

Answer 1

The answer is:
Workers often earned less because fewer businesses were competing for their services

Answer 2

When the industry was monopolized it was controlled by one company without competition, like Carnegie, Rockefeller, JP Morgan. When the industry became monopolized wages went down and when workers threatened to do strikes they would suffer, the government would not help them because of the importance of the industry.
