In life, the basic things we need are:
-Food and Water
-Clothing
-Shelter
Imagine a farmer and a fisherman, they gave what they harvest for free, would everyone do the same thing? If every people and nations followed these 2 men, owning a land will now be regulated, because farming will now be requiring much more land. Anyone will now be able to study. You won't be seeing a hungry homeless person on the street. More and more brilliant ideas will come to life, because funds will no longer be needed but only the skill and the talent, and lastly; no more tax! If these all happens, the only problem will be are lazy people.
