  Altruistic lobbying is lobbying in the public interest or in the interest of
the least protected part of the society. In fact, an altruist has a wide range
of strategies, from behaving in the interest of the society as a whole to the
support of the most disadvantaged ones. How can we compare the effectiveness of
such strategies? Another question is: "Given a strategy, is it possible to
estimate the optimal number of participants choosing it?" Finally, do the
answers to these questions depend on the level of well-being in the society?
Can we say that the poorer the society, the more important is to focus on the
support of the poorest? We answer these questions within the framework of the
model of social dynamics determined by voting in a stochastic environment.
