No if they employed the Scientific method to social sciences you’d probably get the same outcome.
Look bottom line is you guys are throwing out all kinds of nonesense but nothing cited here or presented addresses the underlying fundamental issue that praxeology presents(The very point of this thread). Economic Calculation.
Unless you are omniscient, and you can see the ordinal preferences of every man women or child on earth of every second of every day, your plan for society logically is incapable of working. You are essentially trying to make 2+2=5 by changing the definitions of 2. It just doesn’t add up. Only when you delve into the realm of nonesense and incoherency is such discussion permited because reason can be ignored(Hence the reason communists hide themselves in rhetoric and semantics).
