May Day 1933, as well as an airshow in Berlin and fireworks. The Nazis added strongly nationalist themes to the celebrations, and Hitler spoke of workers as patriots who had built Germany's industrial strength and had honourably served in the war, while claiming that they had been oppressed under economic liberalism. Hitler praised the virtues of labor, and was quoted in the Völkischer Beobachter as declaring that "I only acknowledge one nobility—that of labour." The event proved convincing, as the next day the Berliner Morgenpost, a newspaper which had been associated with the political left in the past, praised the regime's May Day celebrations. At the same time, however, the Nazis sought to destroy independent working class organizations, seeing them as incompatible with the trans-class unity of the Volksgemeinschaft. On 2 May 1933, one day after the celebrations, the trade union movement was banned, and "stormtroopers sealed off and took over the operations of the socialist Free Trade Unions and incorporated them into what became the German Labor Front". The Nazis continued social welfare policies initiated by the governments of the Weimar Republic and mobilized volunteers to assist those impoverished, "racially-worthy" Germans through the National Socialist People's Welfare organization. This organization oversaw charitable activities, and became the largest civic organization in Nazi Germany. Successful efforts were made to get middle-class women involved in social work assisting large families. The Winter Relief campaigns acted as a ritual to generate public feeling. These efforts also served to reinforce the racial ideology of the Nazis and the idea that the Volksgemeinschaft was a racial community, because Jews and other non-Aryans were excluded from social welfare benefits, as were Germans who opposed Nazism or who were deemed "unfit" for other reasons. The Volksgemeinschaft was intended to create a sense of uniformity amongst its members; Fritz Reinhardt, state secretary for the finance ministry, introduced numerous tax breaks for lower and middle class Germans, narrowed pension gaps between blue and white collar workers, and lowered the entrance standards for civil service exams. The ubiquitous uniforms within Nazi organisations were intended to suppress visible class differences in dress and create an image of unity. Between 1933 and 1939, upward mobility was twice as likely as between 1927 and 1933. The Second World War assisted in this, as social status and class did not affect whether one received Reich services. Wartime rationing was implemented in an egalitarian manner,
