What is 'work', anymore? In context of capitalism/communism (and the old industrial economy), 'work' had basically meant a 'worker' getting paid to do some tangible, quantifiable task. E.g. I pay you $5 to move those 100 widgets. Or, maybe you get a loaf of bread if you move those 100 widgets.
But, in terms of the modern, knowledge economy, work means something different. I don't need someone to move widgets. What I need is more content, better design, more aesthetics, more culture, more entertainment, more research and development. None of these are quantifiable or fungible.
Work today should be viewed more like a potential to produce some value. In the startup world, we give lots of money to lots of companies, with the understanding that most will fail. We hope that a few will succeed and produce a new products or services that will work. But, we don't know. We have to spread the money around to get those results.
I have a sister who makes probably a few thousand a year. She's a very high-IQ person, who just happened to take some wrong turns in life. She's gifted and very crafty and creative. But, 95% of her time is taken up by the logistics of life - trying to pay the bills, keep the water running, etc. I would much rather have her be able to focus on creating things and inventing. But, as her brother, I'm not willing to fund her completely, because even with her innate creativity and intelligence, I'm unsure what will result. It's too much risk, for this one individual.
But, on the other hand, everyday, the majority of the value that I get is from things that are 'free': product reviews, blog articles, questions answered on IRC, people posting cat videos. There is a shit ton of work being done, but it's not quantifiable. How much is it worth for someone to read a book and edit a wikipedia page? We're certainly not willing to pay people to do that type of work. But, in aggregate, it's incredibly valuable.
Anyway, my thought is that if we can give people basic freedom from the inane logistics of life, they will free themselves up to do other things. Very few people will do nothing. I can't even imagine nothing. Even the stereotypical images of bums drinking 40oz out of bags - it's not nothing. They're creating something - new words, new art, conversation that ripples. Maybe they go to the library and post their thoughts online - that turn into other ideas. But, of the hours a day that they do things, we can't quantify that value.
Labeling things as capitalism/communism, left/right doesn't seem to do much to help the problem. We should all agree that we're past the 20th century, past the 19th century. We need new ways of thinking about these issues.
We need a system where people who have been born with the competitive gene, and who want to conquer and acquire trophies, are free to compete and be rewarded for it. But, we should also recognize that most people don't have that gene, and that it can't be taught easily. But, those other people should be given some basic income to allow them to explore the infinite space of Human knowledge and creativity.
