I am poor, and if I am blind to economic issues, I will be worse off. I need to be frugal. I need to keep track of the things I am paying. I need to ask myself before each purchase: do I really need it? And so forth... Sure, many poor people might still gamble away their money, or buy stuff they cannot afford, but humans are being humans.
There is a struggle between those who have power and those who don't. This displacement creates blind spots, and also vantage points.
