1916 - Steamship travel. First class vs. steerage.
2016 - Commercial jet. First class vs. economy.
RE: Well, the relatively poor travel just as fast as the rich in either 1916 or 2016. The poor just do not travel as often as the rich or in the same comfort.

Well, the article is not comparing middle class in 2017 with rich in 2017, nor is it comparing middle class in 1916 with rich in 1916.
This article is comparing middle class in 2017 with very rich in 1916 and then asking the question -— who really is better off overall in terms of the necessities and other luxuries of life?
