'I dont know what the american equivalent of big suburban free standing pub is on an estate' There are none of either. Maybe the odd exception that proves the rule. But really, no estates as known in the UK and pubs tend to be seedy in the suburbs and themey in cities (i.e. Oirish, sports, hookup-ey), nothing like your average British pub (or Irish for that matter).
In general, the poor are supposed to be freed from the vices that have made them poor (according to American myth that equates prosperity and god fearingness) before they can ascend to the middle class. So bars and drinking in general are very discouraged.
I don't see the series finding a chord in the US at all. This is the country where some states (most notably Wisconsin) are trying to balance a budget on the backs of public service employees, with many people blaming unions for the sorry state of public finances in many states using the same sort of language reserved for welfare spongers in the UK. There really is no welfare state or consciousness of entitlement to the sort of benefits that the British take for granted.
