Living and working conditions for most peasants were dreadful, famine and starvation were common. People worked for long hours, their wages were low and rent was high. In factory towns people lived in overcrowded slums and there were very few sanitary facilities. The Soviet working class was, according to Marxist–Leninist theory, supposed to be the Soviet Union's ruling class during its transition from the socialist stage of development to full communism. However, it's commonly argued that its influence over production and policies diminished as the USSR's existence progressed. The Russian nobility and royalty only made up under 1% of the population. They enjoyed a comfortable life without poverty. Their children - both boys and girls - could attend schools and universities. They lived in big stone houses in cities and often had one or several country estates.
