When I state that it doesn't matter how an economy is organized I presuppose two things within a society.
1. Agreement on the goals, standard of living, use of resources, etc. of economic activity.
2. Willingness to adhere to rules governing economic activity especially to recognize the potential harm and to channel the energy greed engenders.
Your examples are of successful, S. Korea, or failed, N. Korea, governments, ones that when it came to economics either took the two conditions into account or didn't, performed competently or didn't.  It's up to a nations' citizens to make that judgement.
Do I feel that society owes us all a living?  Of course, what other purpose is there for social structures?  If society encourages uncontrolled procreation then it's obliged to insure that each person has opportunities to work, full employment (anathema to Capitalists), UBI or both to provide for those unable to work.  Economies are choices not laws handed down from on high.
