Increase the Whole Pyramid
It is easy to imagine that if someone moves up to the top, another one will move in the opposite direction, that is down to the bottom. This happens when the pyramid does not grow in its volume. Since space may be only occupied by an individual, if someone gains, another one loses. Therefore
the narrowing of the pyramid's base is not enough. It needs more. Let's thus expand the whole pyramid in volume and we will really make that its 6 billion people enjoy wealth. So we must maintain welfare programmes supported by a strong education system and by infra-structural investments in order to organize economics and promote better incomes distribution. This seems a good starting point to generate real wealth and welfare for long and for all.
