Yes, and growth is sustained by striking a balance of quality and quantity in terms of the human population. If this balance becomes out of whack you will decline into what they refer to as "malthusian stagnation". So the population does need to grow in order to sustain economic growth, along with the quality of the individuals that make up the population. What they refer to as "economic darwinism" beings to truly take place as a population has the extra resources to put more into children than parent, creating generational progress. Post industrial economic darwinism gets a buffer, so-to-speak, due to the increased per capita productivity introduced by technology. However this is also not infinite, and so, at some point this will plateau, and the population will need to begin rising again to spur growth. We are likely in the midst of this plateauing.
For a really bad summary? Capitalism requires economic growth, business, industry, etc. must increase output, therefore the consumer base must increase, and so it goes with the true labor underclass. For a real explanation check the link below to a PDF file of a dissertation on the subject.
There is an old man in my building, who got into video games about 10 years ago, when his wife died. When I first moved in I played games with him fairly often. After I knew him about a year, he exposed himself as racist. So I just faded away from interacting with him, too old to bother lecturing, so I just stopped socializing with him. I do see him around, and we make small talk, in the halls, elevator, etc.
Anyway, now that you have context, I ran into him in the elevator when Shadows first came out. He said he had been playing it, and asked if I had. I said I didn't then told him I was a little surprised he bothered with it. He said "Cause you play a colored samurai?" I said that I figured it wouldn't be his thing, a lot of people didn't like the idea. He replied "He was a real person, though" I told him a lot of people were mad about it, he said "it's just a game". So, if a racist, 83 year old, man didn't see the issue here, these people have to be seeking things to be mad about. He doesn't do much online though. Only social media he does is look at FB when his kids tell him they posted new pics of the grand kids, or whatever. This is purely a symptom of being terminally online.
Greenland, the cowards that ran to Iran after being attacked!
