I would like to defend in this statement the crab mentality, because it is generally consider bad. I like to show, that it could also peceived as good. I just like to broaden the view. :)
Some traditional societies without central governemt implement strict rules to preserve the social status quo of their members. Some of that societies have a hierarchy (with a leader, noble and common men), some not. The aim of that rules are to stabilize these societies and to avoid unrest. If there's no hierarchy these rukes prevent the origination of an upper class.
Most people nowadays abhor these ideas. Individualism and the idea of property (land and others; the more = the more successful = the better) seems to be all right. The quest for equality become outdated, ugly, despicable. It is replaced by charity actions of the affluent.
But for what does someone need millions of dollars? A villa with 20 rooms? A hazienda of 1000 ha?
I know, that all the hard-working people, becoming prosperous in that way, will condem my view as just envy and maybe they are right.
Still I cannot stop believing, that a society, where equality of the people is enforced, is also not the unhappiest of the world.
A well-known, still functioning example are the San in Africa and the Aeta in the Philippines (as far as I know) and tribes in South America, hunter-gatherers, an egalitarian society without society.
In the Philippines the distance between poor and rich is incredible. Maybe 100 families rules the economy of the country and maybe 1% of the people are considered very rich, while 50-60% are considered poor.
So maybe for justice the Philippines need much more of a crab mentality?
This is more a start for a discussion than my final point of view. Thanks.
