I lived in a small town during most of the '70s and have lived in big cities ever since so it's kind of tough to compare from a personal perspective since the differences between small towns and big cities haven't changed that much, other than what resulted from technological advances. Most of what I remember about life in the '70s was me and my friends getting stoned and listening to music, or drinking beer and cruising up and down Main Street.
Cars were a lot cooler looking back then and if you had a luxury car, it was like driving around in your living room. Today's cars are far more reliable and fuel efficient, and cleaner running, which is better for the environment. You were lucky to get 80 or 90k miles on a car back then. Today's cars will go 200k miles and still run just fine.
Music was undeniably better during the '70s. There was so much creativity back then compared to what's going on today. Music in the '70s combined elements of all different genres from country, to rockabilly, to jazz, to bluegrass, to folk, all of which still existed in their original form with a lot of the original artists still making music. The originators of those genres would often play with their younger contemporaries who worshiped them and incorporated those styles into their own original music. So the music was more authentic back then.
Today's popular bands don't look to the original pioneers of music. At least the most popular contemporary bands don't. They copy the styles of the bands of the '70s, and they don't do it as well, so why not just go back to the music of the '70s? The band that comes to mind is Greta Van Fleet. They sound a lot like Led Zeppelin, but they don't have good songs. All they have is the sound, but they're enormously popular and making a lot of money copying Led Zeppelin's style, so you can't really blame them. I don't think anyone's going to look back in fifty years and talk about how great they were, though. I don't think any contemporary band will be highly revered or copied in 50 years.
On the other hand, there is something to be said for the age of the Internet and the ease in which we can access information. Plus, we can interact with people from all over the world in these online forums, so that's something. Politically, we weren't nearly as polarized back then, but things were beginning to move in that direction.
