As Robert Conquest, the great historian of the Stalinist Terror and the Holodomor wrote:

Malcolm Muggeridge describes Quakers applauding task parades, feminists delighted at the sight of women bowed down under a hundredweight of coal, architects in ecstasies over ramshackle buildings just erected and already crumbling away.

Mind-set seems too strong a word: these were minds like jelly, ready for the master's imprint.
