The area in which popular consent had to be upheld had widened constan
tly since the 1930s, as matters such as the supply of capital or wage
bargaining, once regarded as outside the scope of government, became p
oliticised. But since governments' performance could now be measured m
ore easily against their own pretensions to manage the economy, the re
turns from official propaganda in a more sceptical, open society, stea
dily diminished. (Keith Middlemas, 1979:424)
