Making things or selling things is not capitalism. Capitalism is the private ownership of the means of production; things like factories, tools, intellectual property, etc.
On the point of greed, I disagree that it’s just simply “human nature”. However, even if it was, why should we have an economic system that prioritizes greed?
Capitalism is the ideology that defends capital as the main desirable quality in society.
Greed is a consequence of the desire for ownership, which is part of human nature.
Capitalism is the exaltation of that greed… and no, we should not have any system that blindly defends a single aspect of life.
Life is full of nuance, no single aspect should rule it all; sometimes ownership is good (like my pants), sometimes sharing is good (like riding on a bus), sometimes defending a life is good (like preventing a murder), sometimes ending a life is good (like euthanasia)… and so on.
sometimes ownership is good (like my pants)
Anticapitalist critique of private ownership isn’t about private ownership of pants it’s about private/centralized ownership of the means of production. This is a critical distinction, as many models still want a free market which doesn’t work without private property.
