All this Crisis let's be honest:
What crisis? Does a cow produce less milk? Does less oil come from the ground? Does less potatoes grow in the fields? It's not like that, these crises are all lies, the cow still gives milk and food grows enough and oil, etc., everything is enough.
You must really be some 8yo who has been left alone!
Oil doesn't just come out of the ground, cows need to be fed and bred, you need equipment to plow the fields to grow crops.
Once a thing in this chain becomes more expensive the finished product also costs more, once a war start somewhere there is less of that product so less of that finished product.
You will still make the same mount of potatoes from the same batch of seeds but what happens when you have no fertilizer or you have nobody to work the fields? What happens when there is no money the bank is willing to lend you to buy farming equipment?
Stop playing farmville and go to school kid!
Now that wars are becoming less and more peace, there will be even more excess oil.
You have to a special kind of moron to not understand that peace means economic expansion as everyone is happy and thinks about growing their business, traveling and more.
