Interestingly it was the staunch Liberal David Lloyd George who used the phrase "land fit for heroes" at the end of the first world war.
Before WW1 he introduced old age pensions for those over 70 and later introduced National Insurance against unemployment and ill health.
During the 1918 General Election campaign, Lloyd George promised comprehensive reforms to deal with poor education, housing, health and transport… ‘a land fit for heroes’. Although re-elected he remained dependent upon the coalition with the Conservatives, who had little intention of delivering such radical reforms.
