Communism is, contrary to the nature of imperialism, the ideal societal structure and encompasses the most universal benefits rather than the inverse. The individual is not enslaved to the economy in any sense of the term, but rather liberated to the realm of labor compensation and revitalized with an actual meaning--as to serve the collective is to serve the individual. Privatization is the enemy of the collective--the means of production should be seized by the workers rather than a ruling entity. Historically, capitalism has always ushered in the path towards imperial practices--the biggest example of this is the United States, which is the world's largest-growing free market empire, with colonies all across the globe that are pillaged for economic and political domination in their host regions. A Darwinian system cannot supply each and all according to his needs, only a few according to their status.
One is not an individual, but a part of a greater group that is congruent in their being and existential properties as humans; Kierkegaard’s postulation on the absence of individual thought in a crowd loses veracity when it is taken into account that the individual thoughts of oneself are precisely what constitute the sentiments of the crowd—you do not lose volition or personal choice-making skills once you become a part of a significant group, but rather you become a determining factor in the action and intention behind said group. Trade among nations is not the most imperative effectuation that a country must maximize, only domestic stability and internal cohesiveness; prioritizing labor to the nation does not hinder the generation of intellectualism, as it enhances the distribution of goods and services, making it so that the material conditions of the people are in an adequate state to allow for profound thought to take place in a collectivist society (urbanism would not be dissolved, as labor output increase would further industrialization and technological development). Mixed economies still exhibit the socioeconomic detriments innate to capitalism as they do not address the existence of class structures but rather accommodate their presence and solidify the position of individuals within their ranks--this is why democratic socialism is fundamentally flawed in its execution.
Communism does not compel people to acquiesce their denominations and nature to the government—in fact, it’s the opposite, as human nature is allowed to grow lavish to the highest proportion conceivable under such system, and theological standings are allowed to be personably kept to oneself so as to prevent the permeation of ideologies and fundamentalism. As is stated by Marx, religion is the opium of the people, and thus it cannot be abstracted from them so precipitously without some kind of social dilapidation occurring in consequence. Mixed economies manage or disguise class issues instead of solving them by allowing capital to accumulate while installing safety nets to maintain stability and congruence; only extreme inequality is addressed and rectified with progressive taxes—but labor exploitation is still perpetuated and the ruling class still possesses the most political influence.
A society organized into a single class is the most auspicious course of action that an economy can put forth into pragmatic reality, as it deters conflict and brings about a sense of unionization while centralizing the influence of political parties into a bolstered core devoid of functional discrepancies. It can only lead to a latent sequence of separation and the formation of a novel ruling class when executed in a manner discrepant from that which is most ideal, which encompasses the agglomeration of society into a lower, subordinate class rather than a medium, middle-income one—in practice, it wouldn’t lead to the emergence of another ruling force as it’d push for collective ownership of the means of production on all accounts rather than upper dominance.
