Capitalism rose on the back of organized violence, mass impoverishment, and the systematic destruction of self-sufficient subsistence economies. It did not put an end to serfdom; rather, it put an end to the progressive revolution that had ended serfdom. Indeed, by securing virtually total control over the means of production, and rendering peasants and workers dependent on them for survival, capitalists took the principles of serfdom to new extremes. People did not welcome this new system with open arms; on the contrary, they rebelled against it. The period 1500 to the 1800s, right into the Industrial Revolution, was among the bloodiest, most tumultuous times in world history.

The rise of the capitalist class in North America similarly was founded on terrible exploitation. Some enriched themselves through the killing of beaver, deer and other animals for their skin and hair, while other continued and expanded the deadly expropriation of the homelands of indigenous humans and other animals for ranching enterprises. Still others began exploiting children, women and men in mines, nascent factories and fields, where tens of thousands of people were ruthlessly enslaved.

Capitalism relies on maintaining an artificial scarcity of essential goods and services (like housing, healthcare, transport, etc), through processes of enclosure and commodification. We know that enclosure enables monopolists to raise prices and maximize their profits (consider the rental market, the US healthcare system, or the British rail system). But it also has another effect. When essential goods are privatized and expensive, people need more income than they would otherwise require to access them. To get it they are compelled to increase their labour in capitalist markets, working to produce new things that may not be needed (with increased energy use, resource use, and ecological pressure) simply to access things that clearly are needed, and which are quite often already there.

The rise of industrial capitalism thus rested on the maintenance of slavery in another part of the world, even though that slavery was no longer dependent on the continuation of the slave trade.

Capitalist primitive accumulation, the emergence of capitalism in the course of history, means essentially savage and ruthless despoliation of small producers by the bourgeoisie. Capitalism came about by the elimination of small production, the abolition of small producers' private owner-ship based on individual labour and its replacement by capitalist private ownership based on exploitation of the labour of the proletariat through the agency of the wage system.

the new industrial processes which the capitalist system gave the world necessitated the education and mental training of the workers in order that they might be fit and efficient wealth producers. Capitalism therefore created the economic or material reasons far the need of the great mass of the workers to be educated: It "democratized" education.

The rise of capitalism, rather than delivering improvements in human welfare, was associated with plummeting wages, a reduction in human stature, and a marked upturn in the incidence of famine. Progress did not begin until the 1880s in the European core, and the 20th century in the European periphery, the latter roughly a century later than the standard narrative suggests.

It is not enough that the conditions of labour are concentrated at one pole of society in the shape of capital, while at the other pole are grouped masses of men who have nothing to sell but their labour-power. Nor is it enough that they are compelled to sell themselves voluntarily. The advance of capitalist production develops a working class which by education, tradition and habit looks upon the requirements of that mode of production as self-evident natural laws. The organization of the capitalist process of production, once it is fully developed, breaks down all resistance.

Capitalism in the 19th century did not doom the worker to a life of perpetual poverty. Instead, they kept creating new and better-paying employments as the decades went by. They produced the wealth and rising income that resulted in the emergence of a phenomenon completely new to human history: a self-supporting and educated middle class that grew more and more as they lower classes bettered their economic well-being.

The economic structure of capitalist society has grown out of the economic structure of feudal society. The dissolution of the latter set free the elements of the former ... [T]he historical movement which changes the producers into wage-workers, appears, on the one hand, as their emancipation from serfdom and from the fetters of the guilds, and this side alone exists for our bourgeois historians. But, on the other hand, these new freedmen became sellers of themselves only after they had been robbed of all their own means of production, and of all the guarantees of existence afforded by the old feudal arrangements. And the history of this, their expropriation, is written in the annals of mankind in letters of blood and fire.

The progressive historical role of capitalism may be summed up in two brief propositions: increase in the productive forces of social labour, and the socialisation of that labour. But both these facts manifest themselves in extremely diverse processes in different branches of the national economy.

Long before the rise of fascism, competitive capitalism was replaced in each capitalist nation by monopoly capitalism. The markets were controlled by trusts and cartels. The development from laissez faire to monopoly capitalism led to the creation of the world market, the international division of labor, the concentration of capital, and the increase of the productivity of labor. They are all interdependent; one is unthinkable without the others.

However, the peasants and workers of Europe (and eventually the inhabitants of the whole world) paid a huge price so that the capitalists could make their profits from the human labor that always lies behind the machines. That contradicts other facets of development, especially viewed from the standpoint of those who suffered and still suffer to make capitalist achievements possible. This latter group are the majority of mankind. To advance, they must overthrow capitalism; and that is why at the moment capitalism stands in the path of further human social development. To put it another way, the social (class) relations of capitalism are now outmoded, just as slave and feudal relations became outmoded in their time.

Bourgeois class domination is undoubtedly an historical necessity, but, so too, the rising of the working class against it. Capital is an historical necessity, but, so too, its grave digger, the socialist proletariat.
