Yeah I have heard that with a homogeneous group socialism can work but I've also heard it limits what people want to do in terms of jobs. Like if you get a raise make more and have more job responsibilities you actually don't make more so people stop taking these jobs because they come with more responsibility but not more pay because of high taxes on the wealthy / high tax bracket. I love biking cities and have lived this way even in the USA. I am not against convenience I am against control. If you want to live a a city great! If not great! It's the push for control and of course talk of having you're own zone you have to pay to leave which is nuts.
