Socialism doesn't motivate success in the traditional sense - it never has, and it never will. Socialism punishes traditional (economic) success by taking away the fruits of successful labor and redistributing it to those whose behavior (often the result of relative laziness) led to failure. This incentivizes and rewards laziness, apathy, and failure - and it chases away success. For example, how many doctors leave poor socialist nations (where their hard work and studying are rewarded with socialist poverty) and immigrate to the United States (or Canada or Europe or Australia) where they are financially rewarded at a much higher level?
