America has drastically changed over the past 100 years, and anybody can see that. There are multiple different ways that things have changed, too. Technology-wise, America has changed a ton! Cars are extremely common nowadays, as well as smartphones, portable computers, solar energy, and things like that. 100 years ago, we were nowhere near as advanced as we are now. Racism and sexism have also drastically changed over the past 100 years. Women and colored people are viewed in a much better light than they were in the past.
True, this was a quote that was very popular when slaves were around still. Symbolism doesn't always have to describe, usually just gives you a vivid image. I hope this was helpful
