Cutting public services to thread-bare levels is not a fundamental tennet of Conservative policy though. It's simply that Conservatives believe fiscal prudence. I do accept that there is some ideological divide, with Labour favouring a larger public sector and the Conservatives a smaller one. But I do not accept that it is fundamental to Conservatives to have our public services on their knees: it isn't.
I'd like excellent public services for all, and every Tory I know wants the same. Your criticism simply ignores the economic climate we've had to operate in (and indeed that which Margaret Thatcher inherited in 1979).
A huge failing of the Tory campaigns of late have been a failure to explain to the public WHY austerity was needed, and what the vision is for once austerity is over. If people were offered a bright future, they might be more accepting of the pain on the road to get there. And we are nearly there; the deficit already down to more manageable levels. May completely lost the plot in so many ways, but forgetting to mention this at all, was one of the biggest sins.
