If we recall that capitalism simply means the application of capital to increase gross factor productivity, and if the green argument is that gross factor productivity will increase as we move to renewable sources of energy, then it's still capitalism, isn't it? And if capital investment in infrastructure that increases job growth, wage growth, etc. is good, then why should we abandon the practice of allocating capital in such ways? Because this is precisely what capitalism does, when not perverted by politics and standard human stupidity. Perhaps the author doesn't understand what capitalism actually is, and is under the illusion that it means monopoly profits, clinging to old ways, and utterly corrupt government. That is a decent description of the USA, but it is not at all a description of capitalism.
