A friend of mine went out with a Russian girl for 3 years a while back, and every now and then she would regale us with stories of life in the former USSR, of waiting in line for 3 hours for bread, or milk, or potatoes or whatever. Furniture, clothing, paint, you name it, all came from state-run factories. Thus everyone had the same table. The same shirt. The same wall colour. I am exaggerating a bit, obviously, but you can see my point. Also, I think it was in 1984 or 85 that the Soviet government made too little toothpaste, and so had to start an advertising campaign to get people to eat carrots, because they are good for teeth. With state-run economies, there will automatically be less innovation and poor planning, because there will be less competition and thus less drive to design new products.
Computers are a good example. Assuming Intel was the state-sanctioned chip maker. Would computing power be what it is today? Why would Intel worry about making faster chips? The vast majority of what we do daily with computers does not require P4 3.2GHz chips, let’s be honest. But with competition, what is the main way to separate one company’s product from another’s? In this case, speed. So AMD came along and said hey, look at our chip, it’s faster than theirs. Thus Intel was forced to innovate, in order to stay alive. Without this competition, we’d all probably be using 386’s and the SDMB would be a text-based BBS, if it even existed at all.
I can understand the feeling about working too much, and I have read research that stated that we are working more now than at any time in the past century (don’t have the cites right now). But that is the nature of competition and innovation, the more you do it, the more you do it, so to speak. There are ways to regulate work hours, vacation time, etc, it’s up to the government to do so.
The problem also with one-company economies is that it drives wealth into the hands of a very small number of people, smaller than capitalist societies, because only a very small number of people control the means of production. Look at any of the former East Bloc countries, they are full of very poor people and a very, very small number of wealthy.
