"If in-kind contributions from charities is included as "spending" then the family is not taking cash out of its collective pocket to purchase. "
An interesting speculation on your part all right, but nothing in the BLS data provided indicates anything other that spending of actual dollars of income. The BLS data in no way measures or includes charity contributions to the families involved and your claim that it does is indeed made of whole cloth.
And as has been pointed out to you several times, the criteria for the prebate is not taxes paid at all but strictly family size. Your pretense to the contrary is more of the same warped interpretation.
There is certainly no need to "clarify" something which is so crystal clear and which you merely intentionally choose to misstate as the rebate is clearly defined in the bill. Clarifying your misstatements would no doubt be a full time job.
Principled links to a BLS table with no explanatory notes or even an indication of what year is represented in the data. I ask for more information and get back - well - basically nothing useful.
What would you call Regular contributions for support listed under Sources of income and personal taxes? Perhaps that's actual dollars, and perhaps that's in-kind gifts. I don't know because there isn't enough information.
