What defined basic needs? Is it stale bread, a shack, a pre-k education, and the ability to see a doctor once a year? I can guarantee there will always be conflict determining this.

Also is it right to enact socialism only amongst one country/society like the US? If the means of production will get forcefully seized by the state for the greater good, what's to stop this line of thinking from growing to encompass the world in an effort for benevolent colonization?
