NRS social grade as a measure for class

[King of Kensington]

Would something like the NRS social grade (like have in the UK) be helpful in terms of measuring class voting in the US, given the limitations of the "college degree or no degree" proxy measure?

No. Some sort of weighted score of income and years of formal education would be ideal, ideally with weighting factors based on behavioral questions, ie, "In the past 30 days, have you shopped at Walmart?" "In the past 30 days, have you shopped at Whole Foods?", etc.

It is better than using education, certainly, but has its own flaws (i.e. it is much more relevant to the structure of the labour market and society c. 1976 than 2016, the general utter mess of the 'C' categories etc).
