So if the question is whether you would choose to be wealthier than 99.9% of people in the world in 1900, or wealthier than 95% of the people in the world in 2010, I'd say it was a sickeningly decadent question.
But, I'd also say that the lifespan gains between 1900 and now are overstated due to a drastic reduction in infant and child mortality, plays and live music are nicer than video and audio recordings, and instant long-distance communication hasn't significantly improved the quality of my life, just alienated me from my neighbors. The math and intellectual culture was just as interesting then as it is now, if not more, and PR was just a twinkle in Mr. Bernays' eye, so I'd be able to avoid the advertising saturation of modern culture. With the addition of being able to replace any device with an actual person or team of people, there's no doubt to me that life would be better as a rich person in 1900. Just avoid nails.
