I've seen those reports myself. However they don't note anything about the entire class changing. Today even the lowest cast things nothing about having an entire encyclopedia in their pocket (a smart phone), 40 years ago encyclopedias were something you needed to be middle class to have one in your house, and nobody could have them in a pocket (meaning you both could afford one, and the space to store it at home)
Going back farther, 120 years ago cars were the play thing of the super rich. Now the poor have much nicer cars (including options like electric start, not to mention the unheard of AC), that are fast and never break (by todays standard they break down all the time).
