Those are short-term expenses. Families can plan for long-term expenses over years. By your logic poor people would never be able to afford a car. But 80% of people living in poverty do have access to a vehicle.
> Are you really suggesting that all poor families that haven’t spent on test prep are simply ignorantly misprioiritizing spend?
I don't know what the priority should be for doing well on tests. My point is that a $1,400 one-time expense is not out of reach even for most poor people.
And nobody said "all."
> It seems like there’s a massive gap between your life perspective and that of a poor person’s.
I grew up very comfortable, but I have family from Bangladesh who immigrated to pretty close to the bottom of the totem pole. Not the very bottom, not homeless, but public housing, working the lowest end service jobs, etc. My wife's parents grew up extremely poor (as in buying meat at the grocery store was a luxury until she was an older kid). Many people really don't understand the difference between people who are destitute (which is a very small number of people) and "normal" poor people.
