The Ustaše leaders argued that the ordinary Croatian workers and peasants were neglected and exploited in the Kingdom of Yugoslavia. Thus, when they came to power, the Ustaše promised a social revolution, tackling social injustice and poverty. Their anti-bourgeois pre-war rhetoric continued after the establishment of NDH, as well as the strong rejection of a liberal capitalist system. The International Workers' Day on 1 May was specially marked in honor of labour, social justice and solidarity of workers. The regime soon began the mass construction of homes and settlements for Croatian workers. However, their availability was based on social and ideological conformity.
