What we "need" is to eliminate unemployment and poverty while increasing sustainability. That can be accomplished--without redistributing anything--by implementing a "democratically distributed income." [“Same Economy, Way Better Outcomes for Society" here in Medium] (The same process can be used to fund government, eliminating taxes and public debt.)

Eliminating exploitation can be accomplished by expanding that income: making it the income for all employees of any business or government. Having different benefits accruing to different positions, for incentivization, would not be exploitative. ["A Fully Just Economy" also in Medium]
