However if they don't assume that, then they are effectively worsening the 18:82 ratio for other organisations who will be logically and mathematically unable to reach a 50:50 ratio without leaving (82-18)/82 of Y unemployed, so they would be virtue signalling.
So either they assume that, or they are virtue signalling, or they are trying to make (82-18)/82 of Y unemployed. Q.E.D.
