Final answer:
According to Karl Marx, wealth would be redistributed through social ownership of the means of production, where the state controls property and ensures equal distribution for human welfare.
Step-by-step explanation:
According to Karl Marx, in order to redistribute wealth equally among all people, it would be through social ownership of the means of production by the people. Of the options provided, none represent Marx's view on wealth redistribution directly, but the closest is a system where the state controls property and orchestrates the distribution of resources to ensure equality and to serve human welfare, as described in the Communist Manifesto that he co-authored with Friedrich Engels. Therefore, among the given choices, a 'dictatorship of the proletariat' which could involve progressive taxation as a tool, might be closest to Marxist theories, although Marx himself aimed at a stateless, classless society beyond such measures. Free market capitalism, inheritance laws that perpetuate wealth concentration and charitable donations which rely on voluntary private action do not align with Marx's vision for redistributing wealth.
