Is Capitalsim a inherited part of Democracy?

I was once ask this question in Pol 110.  I am curious how everyone wlse would answer

"everyone agrees with his agenda, that everyone be equal and the economy exists to make everyone happy etc etc... anyone can say that."
 
lol socialism/communism is not about everyone being equal, its about nobody being able to succeed. that success is evil, wealth is evil, that using your mind to the best it can and going as far as you can with it is evil. and the biggest one, the needs of the community/government/state come before yours, that being selfish is evil
