Why did trolleys begin to divide cities by class at the end of the 19th century

With the advent of the trolleys, the city dwellers could move from one place to another and develop buildings, suburbs and commute to work and earn their livelihood.

Explanation:

In the nineteenth century, there were a number of innovations and inventions that led to the development of the country. One of such innovations was the advent of the trolleys. With this there was easy commuting of the people from one place to another. They could easily commute to work, they could easily use public transportation build suburbs and live outside cities.

But this led to the division of the people in different classes. Because the people who did not have access to the trolleys could not move from one place to another and was not easy for them to earn their livelihood. Therefore it left some sections of the society as marginalized and the other sections could grow and develop.
