There is much to be said for the idea that pulling up the social ladder lies at the core of all political movements and systems. This is why socialism is so middle class, why covert stifling of social mobility seems so important to both socialism and the many flavours of left wing politics.
Entangled with this is the selective control of information. In other words there is also a fundamental difference between those who value comprehensive explanations and those who for social and political reasons prefer partial explanations. Partial explanations are easier to understand and promote, easier to mould into ladder-pulling slogans.
There is a vastly important type of partial explanation which offers a sense of moral strength while pulling up the social ladder. In these cases the whole ladder-pulling game is viewed from a standpoint of moral strength, Everything is done for the common good, especially for those at the bottom of the social pile.
But of course the moral standpoint is spurious because what is created is dependency and dependency is all that is left once the ladder has been pulled up.
