Question

why does consumption Curve not start from the origin

Answer 1

If Consumption curve starts from its origin, it means that there is zero consumption of goods and services in that region.

This is practically impossible in the real world because even when a person does not earn any money, he has to consume something for survival with someone else's income.

Some Amount of goods or services are automatically consumed by each and every individual.

Answer 2

The consumption curve will not start at the origin because the consumers level of consumption has a minimum level of consumption and so long as the level o f income is at minimum or at zero hence the reason why the consumption curve will not start at the origin.
