When people (Marx and others) say 'capitalism' they usually mean a society based on privately owned 'production'. All of modern society is organized around mass 'production'. Capital is just a means to that end.

Society is being transformed around controlled 'consumption'.

If you look at climate change as an example, all the solutions proposed are limiting consumption and giving government control to regulate energy and other forms of consumption. Other solutions could be proposed, but only limiting consumption is on the table.

This new society is postcapitalist (economically), postindustrial (production), and postmodern (society).

From a postcapitalist point of view, surplus-value or capital, will be taken from the masses and given to corporations or government. From a postindustrial point of view production will come under the bureaucratic control of the state captured by corporations. Postmodernism puts social good above scientific truth, so people will think this new society is better than previous ones.

Postcapitalism solves many of the problems of modern society and the industrial age, but it creates far more new problems.
