Why do you think that the cultural capital of a certain social group is completely isolated and detached from their income level or past history of economic affluence or wellbeing?
What I find from my observations and unbiased reading is that rich people or people with a good track of generational prosperity have better chances to instill in their families the values of entrepreneurship and taking initiative while in poor or less fortunate families this becomes paradoxically difficult to achieve despite the seemingly urgent need to act on.
So, poor families especially the ones with a history of poverty and hardships spanning many generations back are hit on so many levels whether economically, socially or culturally and your thinly veiled attack on minorities communities and the insinuation that their culture product is the reason behind their economic hardships are not really helpful.
