On the one hand, being middle class now is perfectly good and comfortable, aside from probably working a 40 hour week.<p>On the other hand being rich in 1900 not only gives you the freedom to do what you want (within the more conservative boundaries of society and technology back then) but also allows you to travel and see cultures in a way that isn't possible now.<p>If you go to a developing country, people wear t-shirts with slogans on them. Advertising is everywhere. If you went to New York in 1900 it's be completely different to the New York of today, as would Paris, London, Shanghai, Buenos Aires, Istanbul and so on. The cultural differences would be so much greater than they are now, as would the dress, the traditions and so on (perhaps less so for the traditions). Then you start looking further afield, away from the cities. Places like Fuji, Rhodesia, India, the near east etc.<p>To experience those things would be somewhat incredible, perhaps moreso than the global, homogenous McDonalds/Starbucks in every town world we see today.<p>Then there's the experiences you could have. You could watch Sandra Bernhard perform. Go to see the Kitty Hawk's maiden flight. Go to Paris and meet people like Claude Debussy, or to Holland and meet Vincent Van Gogh. Visit Sigmund Freud in Austria, watch the birth of Hollywood and meet people like Buster Keaton, Charlie Chaplin and Stan and Ollie.<p>As for things to see in 1900, you could travel to a still Victorian London and see Queen Victoria's visit. You could go to Australia for the first time (Australia was 'created' in July). You could see the opening of the Paris Metro, and while sipping a bol du Café read about the Boxer rebellion in China. Or you could meet Mark Twain as he comes off the docks back to the U.S. then go to the first Automobile show in Madison Square Garden. It's not as clean cut as you might think.<p>Personally I'd rather be middle class now for various reasons, but I wouldn't rule 1900 out just on the grounds of health or technology.
