Thanks for reading! Those are great questions you ask. Marx thought the workers would eventually rise up to reform capitalism or to overthrow the autocratic systems for producing goods. If the climate scientists are right, we have a short amount of time left to end capitalism and consumerism as we know it or we're doomed. Overpopulation, egoism, global warming, the sixth mass extinction, destruction of the biosphere--these are all major problems that technology and certain philosophies could technically fix, but whether there will be a global awakening is another matter.
By writing about these problems on Medium, we're not even scratching the surface. We're preaching to the converted. Hardly anyone changes their mind, thanks to how the internet creates information silos. Birds of a feather flock together, even when birds have the opportunity to fly with many other kinds of birds. It's depressing and easy to be pessimistic about our prospects.
The rise of China and India might lead the world in a more sustainable direction. Perhaps the problem over the last century has been that the US wasn't mature enough to lead humanity. I've written a couple of articles recently about Chinese pragmatism, which aren't too encouraging. Still, China seems much more rational than the US. But instrumental rationality is compatible with severe corruption.
