except in UK, where the poor and uneducated are stereotypically labour/democrat supporters, wealthy educated types are tory/conservative.

That use to be true in the US too and in some ways still is...but the US also has the race issue which tends to further complicate everything. Working class whites use to be democrats for economic reasons (labor) while still being socially conservative, now they're almost entirely republican and mostly it seems for social (really, ethnic) reasons.

In the US republican affiliation is (or used to be) actually more closely tied with college education and higher income and that is the "fiscal conservatism" (basically lower taxes). Of course higher education levels and income also correlate quite closely with ethnicity and whites are mostly republicans....

Basically the political divisions have become quite ethnically polarized so the usual correlation between actual socio-economic interest and party affiliation don't hold the way one would expect.

Not sure what data you're looking at but Yougov says the exact opposite.

I can't tell if you are ironically making my point or not.
