Keynes, in chapter 24 of The General Theory, announce the mechanism that would lead to the end of "Capitalism",
it would mean the euthanasia of the rentier, and, consequently, the euthanasia of the cumulative oppressive power of the capitalist to exploit the scarcity-value of capital. [...] I see, therefore, the rentier aspect of capitalism as a transitional phase which will disappear when it has done its work.If I am not wrong, Keynes thought that the capital would never change. In other words, that there is not technological change that increase the diversity of capitals, making the 'new type of capital' scarce.
I am not sure, whether Keynes prediction will eventually work. However, it seems to be that there are organizations that are thinking about alternatives to the pure individualism. It seems to be that there is altruism around and it is possible to coordinate it in order to obtain 'efficient and well distribuited' results.
BIEN, is an alternative way to think about the distribution. Take a look at it, and have a thought.
