However the track record for developed countries communally sharing "intellectual property" is much much better. Universities, open source, and public domain all have some crossover with the ideals of socialism.
Yes, communism has repeatedly failed spectacularly.
The softer socialism of public welfare has worked (so far) for many countries including the US. Although I'm skeptical about the future given modern demographics and our governments' choices to appease a majority. The governments of most developed countries smell socialist to me. I'm from New Zealand and most private income/property is taxed up the wahoo to pay for our social welfare programs: it doesn't take much squinting to see my own society as broadly socialist.
Somehow I see people in the US complaining that the Chinese are beating the US at capitalism (regular complaints of price undercutting and monopolistic behaviours) - what's weird since the Chinese are supposed to be pinkos.
