Stimmt!
What is so funny is that so many things that were for the very poor in Ye Olde days are now so fashionable with the rich. Samphire was very much poor man's asparagus. Same for so many local peasant regional dishes. Or thatched houses, or wooden chalets, etc, etc.
But for many very hard working women at the top of their game, a nanny is essential to give stability and safety, and allow some flexibility. Daughter is often delayed at last minute because something goes wrong with a project, or because the trains are not running, or somebody has jumped on the line, etc. Are we saying that it is 'middle class' for a woman to want to reach the top of their career - and still be loving and devoted mums, but with flexibility built into the system?
