Those 10 extra are STILL left without a chair, at this point we would have t conclude that it cant just be the age gap keeping them without seats, they must not hear as well, or run as fast or something Just the disparity cannot explain how these 10 are still let standing round after round
It actually could in shidduchim, although in chairs you’d be right to assume there was a specific difficulty getting a seat.
In musical chairs, it doesn’t matter who sits in which chair.
If that were the case in shidduchim, the analogy would work. However, in shidduchim, the new entries, say the 23 year old boys, are unlikely to marry, say, a 34 year old girl. So even if in theory every girl had exactly the same qualities, the very fact that they have been playing musical chairs for a while (in other words, their age), is a prejudice against them. This wouldn’t be the case in actual musical chairs.
