They've been tried elsewhere, and they usually work out pretty well.
Countries that try them may not be utopias, but they do have consistently high citizen satisfaction scores.
Perhaps a little more realism and a little less moralising would be helpful.
To add: these science programs are good examples of collective action. Can anyone seriously imagine Facebook or Google paying for a project like Cassini?
I am a Communist, and I will say that a slogan is neither something to build your country upon, nor something to criticise a country on. No country has thus far managed to progress past capitalism, certainly not the ones you litsted nor the ones GP listed. Marx was referring to how life ought to be under Socialism, rather than an implementation of this principle under a capitalist system, which he believed was impossible.
