Post-scarcity economy

Post-scarcity is a theoretical economic situation. It supposes a situation where most goods could be produced in abundance with minimal human work. Thus they become cheaply available or even free. 
Post-scarcity does not mean that scarcity has been eliminated for "all" goods and services. It supposes people could have their basic survival needs met, plus some significant amount of their desires for goods and services. 
In the present day, the idea of a world without needs is a fiction. Rather, the increasing population of the world may give rise to many problems. In 2017 the United Nations Population Division projected that the world's population will reach about 9.8 billion in 2050 and 11.2 billion in 2100.
