Modern people have so many benefits that people in the past didn't. We live in big houses, drive cars, live longer, etc. Consider that healthcare has improved 10 fold. Education has improved. Our modern advances make life in the past unfathomable. We have commodities now that people would have fought wars over years ago.
People of the modern world can experience a better lifestyle due to the fact that advancements in technology have allowed society to produce more with less time, effort, space, and materials. Crops grow bigger, stronger, and fuller in less space than they did in previous centuries. Production of goods has become more efficient and streamlined that fewer people can get more work done allowing more free time for leisu activities.
While one could easily say yes, I feel that we are not better off today than the past lifestyle. People today are to dependent on technology. Kids cant do simple math without calculators. Everyone is so rushed and always on the go. The simple life and simple way of doing things have disappeared.
I do not think modern people enjoy a better lifestyle than people in the past. Technology has improved over the years which has made life easier but has also added more stress to our lives. More can be accomplished in less time, but as a result more is being asked and expected of of these days. In the past, you went to work, came home, enjoyed time with your family then went to bed and that was your day. To me, less stress is more enjoyable.
While we experience an easier lifestyle I do not think it is a better lifestyle by any means. People in the past had better lifestyles because things were smaller. People had to interact with each other so everyone knew everyone. People were quick to help out their neighbor or the stranger walking down the road. Now nobody really talks face to face anymore and kindness is rare.
