In general, the main difference between socialism and capitalism is that socialism calls for a division of wealth among the population while capitalism encourages the pursuit of self-interest. 

Capitalism- means of production and distribution of goods and wealth are controlled by individuals and operated for profit. The government does not control or regulate buisness of individuals
Free market and trade
Supply and demand
