Except, of course, in most of the civilized world, including most of Europe and Scandinavia. I doubt you really even know what socialism is. Too many equate it with government control and communism, and it really has nothing to do with either of those concepts.
Our highways and roads are a form of socialism – are you proposing that everyone should individually decide whether to pave the street in front of their house and individually bear that cost? I doubt it.
The real question that should be asked in matters that have broad social impacts is “What is the most cost-effective way to achieve our collective objectives?” If it’s about getting a pizza to eat, it’s hard to make the case that one should socialize the process. If it’s about deciding whether someone can get anything to eat, it’s a wholly different question and some amount of social support is called for.
If it’s something much more important, like healthcare, then it’s about making sure no one slips through the cracks, especially when the non-socialist alternatives are as inefficient and more costly as they are and which lack any rules to assure that no one falls through the cracks.
So, when you blithely assert that socialism has never worked well, you need to put this through the prism of “as compare to what?” When you do that, you find it’s not about labeling something as “socialist” or “capitalist” but, rather, about what yields the greatest benefit to society for the cost incurred.
