Poverty is relative in every society, if for instance in the US you could not afford an internet connection you would be at a significant disadvantage so yes its a required basic of life in a modern society.
Would you consider adding to the list a compulsory insurance scheme for injured workers? The right to to join trade unions? The right to strike? The right to have unions represent workers in collective bargaining?
Most people are fantastically ignorant about the history of socialism. Worse are Americans who are generally fantastically ignorant about everything. If you look at say the Soviet Union in the early days after the civil war and before collectivisation and forced industrialisation under Stalin (He basically took Trotsky and Preobrazhensky's position after he had liquidated them) it basically was a mixed economy the state handle power, water, railroads and so on and industry more or less continued as usual under the guidance of the local soviets. People have this idea that a socialist state is necessarily collectivist, this is not the case.
Many on the right would criticise the Welfare state that dominated post war Europe and Australia as a form of socialism and it was, it was effectively a new deal for workers after the destruction of the depression and two world wars. In Australia this took the form of widespread public ownership of utilities, banks, key industries and facilities like ports and airports, airlines and so on. What this represented in my opinion was a form of democratic socialism, these resources provided for all Australians. Their sale in the the last 40 years represents a great theft off the Australian people as a whole. A transfer of wealth from all to a few, at a great cost to the many. The Milton Friedmans of the world and the market fundamentalism they unleashed on the world after the 74 oil crisis and stagflation is one of the quieter revolutions and assertion of class power in history. Within two generations the common wealth of a raft of developed nations was transferred into the hands of the middle class and elites at fire sale prices and not a shot was fired. (in the developed world anyway, many died in the third world at the hands of their own government implementing the plans of the IMF) The consequences for people in Chile were horrendous.
