Dominate

I might have a flight of idea yesterday and did not make it clear what the worrying bit is.

No, it is not (only) a daddy's kind of concern about overspending children.

Let's come and think of it: Why do our students appear so well off and choose a grandiose place for the graduation dinner ? (I presume it is plain obvious that they do understand they don't need an expensive meal to impress their teachers, as I discussed yesterday.)

There are only two possibilities. Either most of our students are really having a surplus supply of money, or there is a selection bias. The latter is pretty easy to imagine: money is an excellent loudspeaker and, in a group of people from all walks of life, the opinion of the rich often dominates.

But if we see it in an university classroom, that's worrying.

PS. Ironically, poverty is the best loudspeaker in our society. That's another story.
