We certainly seem to be going down that route these days, what with all the talk from Labour/Tories etc to appeal to "working people". I think it's a really annoying euphemism along the same lines as the nebulous "middle class" Republicans and Democrats try to appeal to in the States. You know, nobody can say the words "working class" anymore because you'll get rejected as some kind of 1970s fossil; at least if you use "working class" now you can use it to refer to a class of people who, though they should be "working", no longer work and suffer terrible unemployment. The expression "working people" airbrushes the group that needs help the most (those in depressed former industrial centres) out of the picture in favour of all sorts of middle class people.
I think it's probably a good thing we don't use "middle class" as much as the Americans though, because in the USA it helps to perpetuate the myth that people from very impoverished backgrounds are just middle class people "in-waiting". We've still got that problem over here thanks to Thatcher, but maybe the economic crisis is starting to shift that, or at least highlight the flaws in that right-wing ideology.
I should add that I believe people should have the right to pursue their dreams and so on, make a lot of money and improve your social circumstances, but not everyone has the right mindset or is lucky enough to be able to do that and it would be a terrible shame if those that couldn't feel somehow inadequate.
