A major difference between socialism and capitalism resides in how likely meritocracy is to flourish .
Socialism, in its rightest essence, would ensure that every individual within society enjoyed the same opportunities at the core (quality health, food, education). Naturally, some of these subjects would thrive more than others and therefore be promoted by society to hold higher levels of responsability and reward.
However, the lesser gifted would never be at a disadvantage. They could still count on standard quality support by the same society and equal opportunity for their offspring to pursue their own ambitions.
On the contrary, capitalism creates a societal gap by supporting inherited advantage. In summary, a capitalist society provides better core opportunities for a group of citizens and their offspring regardless of their innate ambitions. The disadvataged group and their offspring then receive a less than standard core support which predisposes them for hardship in the pursue of societal reward.
