Who cares if they are poor or not? He did it as a Christmas Gift.... Does every gift you give at Christmas only go to the needy?
However, generally speaking Layaway is overwhelmingly used statistically by those who are in need over those who are higher up the socioeconomic spectrum.
Khalil Mack apparently cares, because his foundation specifically says he wants to target under-privileged youth. You may notice no one is paying off shoppers’ debts at the Nordstroms or Christian Dior stores. Yes, I understand Walmart lay-away shoppers are probably at the lower end of the wealth distribution. Given that 25% of his gift was apparently stolen, perhaps there are more efficient ways to reach the truly needy.
Anyway, its very generous of him, but I hope he is reaching the people he wants to help.
