Answer:
Right off the bat, we can say that we have technology that our ancestors didn't have during their age. Second, we have education. People back in the day don't get proper education because it was scarce. Lastly, we have public works. During old times, people from one rural area have to rush to slightly urban areas to treat someone in case of a medical emergency. The roads are not the best. These are the things that came to my mind and I know there is more.
