  We formulate a mathematical model of competition for resources between
representatives of different age groups. A nonlinear kinetic
integral-differential equation of the age aggression describes the process of
redistribution of resources. It is shown that the equation of the age
aggression has a stationary solution, in the absence of age-dependency in the
interaction of different age groups. A numerical simulation of the evolution of
resources for different initial distributions has done. It is shown the
instability of the system and the existence of regimes leading to a
concentration of resources in the certain age groups.
