If you define pverty as earning less than 15 % of the median country wage and then pay 90 % of people 2 dollars a day and 10 % of the people infinity dollars a day you have no poverty by definition. Some variation of that is how every other system of government/economy has beaten poverty. There is no point engaging these people unless you are a psychiatrist trying to help them with their mental illness.
Even easier than that, simply define poverty as a property of capitalism and if anybody says that poverty also exists in your communist society, you throw them into the gulag for spreading capitalist propaganda.
Could you give an example of where this has worked?
