*Algeria's GDP is 230 B$, *Oil & Gas account for 30% (70 B$)
My simplistic reasoning would say : Substract 70 from 230 and get a new GDP of 160 B$.
But I know that the concept of GDP is more complex than that: it also includes government spending :
*Government consumption accounts for 30% (70 B$) *60% of the budget comes from Oil & Gas : 42 B$
So I'll continue substracting: 160 - 42 = 118 B$, the new GDP...
But still, I think it's too high: the household consumption accounts for 35%. Most purchasing power comes from fake jobs created by the government, if there were no Oil & Gas these fake jobs would not exist.
Should I still substract this component from the total GDP?
Is my reasoning correct?
