Ok, firstly I assumed you ment electricty generation, not mass murder. The latter is something that I don't think we should be proud of, no matter how ground breaking it is.
Most fission as is made around the world now is due to innovation by the capitalist system, the greatly improved reactor designs that can't fall in to positive feedback etc are all entirely as a result of this. I'm not saying we have a completely un-governed capitalist system either, personally I think we always need a balance of research grants so that fields are not ignored because we don't understand how to make money from them, an example that springs to mind was Xerox's famous lab.
So the apollo program? What do you think the greatest outcome of that has been? For some reason the first one that pops in to my head is the smoke alarm or perhaps the microwave oven. Both owe their sucess and impact in our lifes due to capitalisim. Sure every now and again the fire department hand out 'free' ones, but its the efficency that is inherient in the capitalist system that has made them in appear in almost every home.
Then we go on to the jet engine, right now the most exciting development in it is the long fin fan blade designs. Again this is not a product of war, this is a market driven demand!But at the same time as the apollo program was going on, those same government programs were spending money that they didn't have, what difference could that money have made to education or healthcare?
You know nothing about Ho Chi Minh.
You talk about the idea of there been plenty of farm land to feed people, well capitalisim as we have it is still the best at doing that!
Somewhere like vietnam which wasn't a fascist (also I don't think of fascisim as a dirty word, its often wrongly asociated!) nation, but it did have a controlled farming pratice. People were not given the choice, they HAD to produce the rice to feed the nation. They didn't.
Those who ignore history are doomed to repeat the mistakes. Sure our system isn't perfect, it isn't fair, but its the best damned one we've ever implemented.
I would also love to actually see some suggestions on how to fix these things, rather than the assertions constantly that 'its broken'.
