Socialism itself is scientific, the problem is reliance on vulgar empiricism over using empiricism to supplement dialectical materialism. To use a comparison, engineering begins by understanding the laws of physics, then proceeds to apply these laws and create a prototype, before relying on empiricism to refine and improve. Theory in this instance is the study of the laws of social science, and this is tested and affirmed with practice. Your approach denies the theory and overly relies on iterative micro improvements, which can be disastrous while we already have identified root causes of modern ailments as well as solutions.
This is how socialist countries already knew socialism was the answer before implementing it, which they then work on gradually and iteratively improving once it is established.
