As the socialist majority grows, when socialism is within the grasp of the working class, then will be the proper time for making such important decisions. The only thing socialists can say now, about administration, is that socialism is only socialism if it is democratic. In a socialist society, there will be no money and no barter. Goods will be voluntarily produced, and services voluntarily supplied to meet people's needs. People will freely take the things they need.
Humans behave differently depending upon the conditions that they live in.
Even very short term changes in those conditions can change the way people behave. Human behaviour reflects society. In a society such as capitalism, people's needs are not met and reasonable people feel insecure. People tend to acquire and hoard goods because possession provides some security. Under capitalism, and the previous systems, people have good reason to worry about tomorrow - they can lose their jobs, or be injured, or grow old, and need a cushion of wealth to fall back on.
