mimetic rivalry, n.All

Mimetic rivalry (n.) does ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠not fade with age; adults, like apes, have merely learned to fear it and to hide its crudest forms.

Mimetic rivalry (n.) needs ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠no scarcity: put as many identical toys as there are children in a room and the toys will still not be shared without quarrels.
