There is a one simple fact.
ALL RESOURCES ARE LIMITED.
This is a simple fact that cannot be changed and cannot be questioned.
Of course we can find ways to optimize usage, to get new ways to get specific resource etc. But at the end every resource is limited including workforce(energy).
Because of that its impossible that everyone will get everything. There must be way to redistribute resources THAT ARE LIMITED among people.
For now clean capitalism is the most natural and the most fair way for that. You provide something(work for someone, do something productive sell something etc.) you get coin (an object symbolizes value you gave to society) and you can exhange it for something else (some item or service), value is based on needs for something and how hard is to get something, there is no need to control because if someone doesn't provide any value to society, he wont have access to stuff from other members of society. Simple, effective, fair.
Communism is basically making that big pile of valuables where anyone can take as much as he wants and put as much as he wants. But because humans are by nature greedy and lazy, most of them will just take and will refuse to give anything so that pile will quickly dissapear, so there must be someone who controlls that people will give equally and take equally, but then that group or person simply has control over all valuables and basically there is nothing stopping it fron just hoarding all of it for itself, force people to add to pile and then give them scraps.
