I want to know the answer to the following question:
Who believed that action needed to be taken to level out the social and economic playing field before natural selection could occur to improve humanity?
All the background I'm provided with is that "While some, like Spencer, used analogy from natural selection as an argument against government intervention in the economy to benefit the poor, others, including Alfred Russel Wallace, argued that action was needed to correct social and economic inequities to level the playing field before natural selection could improve humanity further.". Is that enough to answer the question?
