Is it the result of racism that it is so unusual to see young black children with valid money orders?

We're used to seeing "racism" as the action of some individual bus driver pointing someone to the back of the bus, or some individual water fountain monitor pointing people to a different water fountain. But that form of racism was much more common two or three generations ago, and didn't just affect the lives of people who lived then, but also affected their descendants. There may be no racist bus drivers today (and even that story leaves out that the bus driver was undoubtedly under racist orders by their own employer), but we still have the lasting cultural impact of racism to deal with.
