What you say here is only part of the problem. the culture of that group and their up bringing as children, the general attitude of their parents and past generations play a very big part in a persons likely hood of any success. Often they are due to the factors I have stated already programed to fail before they have even left school and possibly before they even went to school. This lack of understanding also leads to the few who manage to succeed as being held up as examples with the words " if they can do it anyone can" This is a ridiculous pronouncement as the said people are the exceptions and are exceptional and to expect all of a said group to be exceptional is bloody ridiculous.
It will take a lot of effort in any deprived group, particularly with the children and probably over several generations to lift them up to another level.
With respect, not so.
I’m deliberately not going to name names, because this does not need to become political, but...
I can point to a racial group in this country - in which I have family - in which over 50% are economically and socially indistinguishable from the rest of society. At levels like this, it becomes blindingly obvious that group membership is not the determining factor. At the same time, there are sub-groups into which huge resources are poured, yet amongst them, violence and substance-abuse are endemic.... and children are actively discouraged from attending school or getting useful skills.
Actually I will name one, because I have ancestry amongst them. The Irish.
Most Australians are familiar with the Ned Kelly mythos in which Ned claimed to be rebelling against the English on behalf of the poor, downtrodden Irish. Reality is that Ned had a gift of the gab and a penchant for stealing other people’s property, something he later boasted of doing on a large scale before he became notorious. Ned had never seen Ireland. In contrast, there were more Irishmen in the Police Party at Stringybark Creek, than in the Kelly Gang. The Judge who sentenced Ned to death for those murders, was Irish-born..... and to top it off, in the year that Ned was hanged, the Irish-born leader of the Eureka-Stockade rebellion - Peter Lalor - was elected Speaker of the Victorian Legislative Assembly.
The fallacy is in arguing that “anybody” can succeed, because not everybody can succeed in any group. The vast majority lack the skills, intelligence and drive necessary. What matters, is that membership of a particular group does not deny you the opportunity.
