I want to know the answer to the following question:
Affluent American families are what type of families?
All the background I'm provided with is that "Episcopalians and Presbyterians, as well as other WASPs, tend to be considerably wealthier and better educated (having graduate and post-graduate degrees per capita) than most other religious groups in United States, and are disproportionately represented in the upper reaches of American business, law and politics, especially the Republican Party.". Is that enough to answer the question?
Answer: no
