The idea of National Socialism is not the "Socialism", it means establishing a "society" based on solidarity, that is build on the "nation", i.e. one ethnic group as a whole.
The economy should only serve the nation that is the people and their state, the government serves as lobby for national interest and bans, nationalizes, privatizes or subsidizes individual businesses, depending on their use.
Generally National Socialism supports or accepts the notion of socio-economic classes, like the aristocracy, urban bourgeoisie, industrial proletariate, rural peasantry or economic moguls, as Long as class differences serve to the benefit of the nation and don't divide it.
Industries and business would stay private and with low-taxes, though they had to ensure good worker's conditions. Banks would be nationalized, while unions were banned and the state was actively employing people.
Economic freedom was present, though as long as you were contributing to society in some way.
Instead of redistribution, National Socialists were corperative and used the tax revenue from the free market economy, which they aided through protectionist action and monetary monopoly, to fund state and social projects, which would as well aid the economy, through reducing inflation, increasing employment and increasing productivity, as well as the ability of the citizens to spend their money on consumer goods and housing. Every man was obligated into education, national labour service, military service, then buying their own land and founding a family, which they would support on their own, though subsidized by the state. poor would generally be aided by organized charity, then mostly employed in state projects.
What Marxist Socialism democratically wants to achieve, is to offer citizens state-funded welfare, child benefit, healthcare, pensions and education, while increasing taxes on rich citizens and privatizing big business, also instituting a one-party republic.
