> 47% of Americans cannot meet a $400 emergency expense.
As I pointed out above, this does not seem to be a correct interpretation of the actual survey data involved.
> You deny their poverty?
Yes, given that the claim is based on a misrepresentation (or, more charitably, misunderstanding) of the actual survey data.
I do not deny that there are plenty of people in the US who are in terrible financial shape and really would be thrown for a loop by a $400 expense. They do not make up 47% of the survey population.
The other interesting question that I do not have an answer to is whether the survey sampled individuals or households, and hence how to translate the survey percentages to population (of non-dependent adults?) percentages.
