We come mentally of age when we discover that the great minds of the past, whom we have patronized, are not less intelligent than we are because they happen to be dead -- Cyril Connolly, The Unquiet Grave
Does that(the patronization) happen frequently? I far more frequently witness people lionizing people of the past in all sorts of benign and malign ways.
Iceland already has freedom of movement (to live and work) due to its EEA membership; and it is only somewhat to do with Schengen, which is about passport free travel not living and working. You can have FoM without Schengen - e.g Romania until 1st Jan 2025.
